This paper studies the architecture of barely visible impact damage (BVID) to comprehend the extent of damage on quasi-isotropic CFRP laminates of varying thickness (i.e. 16, 24 and 32-ply laminates of 3, 4 and 5 mm respectively). Methods: Quasi-static indentation is chosen to produce BVID on CFRP laminates, followed by using non-destruction evaluation method, namely conventional contact-type ultrasonic testing (UT) and C-mode scanning acoustic microscopy (C-SAM) method. Results: The findings revealed (1) the size and shapes of the BVID on CFRP laminates, (2) no damage found at the point of damage, and (3) the bridging between the point of impact to the outer damaged diameter due to the consequence of diverse orientation of carbon fibre strips which exhibit excellent mechanical properties before structural failure. Conclusions: The results concluded that the UT and C-SAM method can identify both the pristine region and the internal damaged structures in CFRP laminates.","PeriodicalId":29806,"journal":{"name":"Materials Open Research","volume":"48 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66549712","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The article aims to explore mycelial growth and analyze the necessary conditions for its development and durability showing its visual potential as a material to be included in a design project. We have explored the aesthetic and metabolic opportunities of the Fungi Kingdom for the design and production of new materials. Methods: Taking the processes that are commonly implemented in biology and by adopting them into design processes, we grow filamentous fungi and isolate them in pieces designed to show and guarantee their natural development, exposing themselves to stress variables such as temperature, humidity, and substrate, among others. Results: Perpetuity is evident after nine years of cultivation; the colonies remain in the container preserving their morphological character and the pigmentation presented from the beginning of incubation with a slight variation in the saturation of the colors. Conclusions: Depending on the species of fungi used and the stimuli applied by the designer, a wide variety of textures, shapes, and colors can be propitiated, generating new product languages and artifacts where their aesthetic qualities are maintained over time.","PeriodicalId":29806,"journal":{"name":"Materials Open Research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47636469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Shanthraj, J. Quinta da Fonseca","doi":"10.12688/materialsopenres.17516.1","DOIUrl":"https://doi.org/10.12688/materialsopenres.17516.1","url":null,"abstract":"Background: Formed aluminium alloy sheet materials are increasingly adopted in production processes such as vehicle manufacturing, due to the potential for weight-saving and improved recyclability when compared to more traditional steel alloys. To maximise these benefits whilst maintaining sufficient mechanical properties, the link between formability and microstructure must be better understood. Virtual materials testing is a cost-effective strategy for generating microstructure-informed formability predictions. Methods: We developed an open-source hybrid framework, combining experimental and computational tasks, for generating reproducible formability predictions. Starting with experimental texture measurements and stress-strain curves, we calibrated crystal plasticity (CP) model parameters. The framework used these parameters to perform a large set of multiaxial full-field CP simulations, from which various anisotropic yield functions were fitted. With these anisotropy parameters, we then employed a Marciniak-Kuczynski finite-element model to predict forming limit curves, which we compared with those from experimental Nakazima tests. Results: We executed the workflow with the aluminium alloy Surfalex HF (AA6016A) as a case study material. The 18-parameter Barlat yield function provided the best fit, compared to six-parameter functions. Predicted forming limits depended strongly on the chosen hardening law, and good agreement with the experimental forming limit curve was found. All of the generated data have been uploaded to the Zenodo repository. A set of Jupyter notebooks to allow interactive inspection of our methods and data are also available. Conclusions: We demonstrated a robust methodology for replicable virtual materials testing, which enables cheaper and faster formability analyses. This complete workflow is encoded within a simple yet highly customisable computational pipeline that can be applied to any material. To maximise reproducibility, our approach takes care to ensure our methods and data — and the ways in which that data is processed — are unambiguously defined during all steps of the workflow.","PeriodicalId":29806,"journal":{"name":"Materials Open Research","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43924542","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chemisorption involves the formation of new chemical bonds between adsorbed species and atoms of the substrate. Adsorbates dissociate on the metal surface because of weaker intermolecular bonds on the surface. The adsorption energies of 12 adsorbed species were calculated on Ni(111) surface. Moreover, 21 elementary reactions were considered for investigating the mechanism of water–gas shift (WGS) reaction on Ni(111). A detailed thermodynamic calculation of the WGS reaction is shown and discussed in this work. The vibrational frequencies were calculated for all the gaseous species, top surface layer atoms, and adsorbed configurations. Thermochemistry of the surface reactions was calculated using spin-paired DFT with RPBE functional for exchange and correlation. This report covers the adsorption energies, vibrational frequencies, and thermochemistry of chemical species such as H2, H2O, CO and CO2, involved in the WGS reaction, on the Ni(111) surface. Vibrational calculations were performed only on their favorable sites. Finally, the thermochemistry ([Formula: see text]E, [Formula: see text]H, [Formula: see text]S, [Formula: see text]G) of elementary reactions was calculated, and thermodynamically driven reaction mechanisms were determined for the water–gas shift reaction on Ni(111) surface. We found that thermodynamically predicted mechanisms are in good accord with the kinetic predictions and can be considered a good first approximation.","PeriodicalId":29806,"journal":{"name":"Materials Open Research","volume":"31 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86750128","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Design for sorting knitwear: Exploring blended textile wastes and the relationship between sorting, recovery, and recycled blending in yarn manufacture","authors":"C. Hall, K. Goldsworthy, R. Earley","doi":"10.12688/materialsopenres.17478.1","DOIUrl":"https://doi.org/10.12688/materialsopenres.17478.1","url":null,"abstract":"Background: The problem of difficult-to-recycle textile waste is an ongoing challenge.  One of the issues is the lack of exchange between the recovery sector and design/manufacture of recycled materials. This paper seeks to addresses the gap in knowledge between sorting (in recovery) and blending activities (in manufacture), expanding current design strategies towards textile recovery. To achieve this, the research explores sorting practices of wool/acrylic blends in the mechanical wool recycling industry and applies this knowledge to the design of new yarns. Methods: A bricolage of methods was used to conduct this research in three parts. First, an overview of a previous study by Author1 is presented from which this research builds. Second, field research using conversation methods with the owner of a closed wool recycling company was conducted centring around their material archive. Thirdly, practice research was conducted in a spinning facility where Author1 applied knowledge from part 1 and 2 by designing four recycled yarns. This was supported by interviews with a sorter and recycler to expand on the findings.   Results: Four methods of sorting and the sorting grades/thresholds that are found in the wool recycling industry are outlined, and five methods of recycled blending historically used in the wool recycling industry are established. This knowledge (sorting methods/grades and recycled blending techniques) were applied in practice and from the methods employed, the relationship between sorting in recovery and recycled blending in manufacture was established across three themes: fibre quality, fibre type and fibre colour. Conclusions: The paper concludes that understanding the link sorting and blending provides the foundations for a ‘Design for Sorting’ methodology. When lessons from each theme (quality, type and colour) are combined, this enables fibre value to be retained in recovery and thus, provides a route for longevity of our textile fibres.","PeriodicalId":29806,"journal":{"name":"Materials Open Research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47199602","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
