These versatile materials have shaped the modern landscape, from towering skyscrapers to highways and bridges. While their primary use has been structural, recent advancements have shown that their widespread presence can also be leveraged for energy conversion and storage. In recent years, various construction methods have been developed that use cementitious composites for energy solutions, such as rechargeable concrete batteries, cementitious thermal energy storage (TES) devices for concentrated solar plants, thermoelectrical concretes and the emergence of radiative cooling concretes. This work aims at reviewing these novel applications. In particular, I will initially explore how rechargeable concrete batteries could offer a sustainable and cost-effective solution for storing energy in buildings and infrastructure. Later I will move on presenting new cement binders whose resistance to high temperature cycles fits well with the stringent requirements of the TES devices in modern concentrated solar plants. The challenges of thermoelectric concretes will be discussed afterwards. Finally, the paper will spend some time on the recent advent of radiative cooling concretes and how they could help reduce energy consumption and mitigate the urban heat island effect in cities. Overall, this work aims to emphasize that if properly engineered, cement-based materials have the potential to revolutionize the way we think about energy storage and conversion in the built environment</div></div>","PeriodicalId":20518,"journal":{"name":"Procedia Structural Integrity","volume":"67 ","pages":"Pages 23-29"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144572448","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 material mainly contains (in wt.%): 9Cr-0.1C-1.4W-0.2V-0.06Ta with strict control on radiologically unfavorable elements (e.g., Mo, Nb, Co, etc.). The creep properties evaluated at 823 K was analyzed for the evolution of creep strain and damage of the material by continuum damage mechanics-based Novel Sin-Hyperbolic model. The model has been implemented in ABAQUS finite element analysis software for predicting the creep curves and rupture life. The model formulae have been incorporated in a user defined subroutine named VUMAT in ABAQUS, with an explicit integration algorithm integrated into the subroutine. The elastic-creep FE axisymmetric analysis for 2D specimen was adopted to reduce the computational time. The creep data for modelling was obtained from the tests conducted at a stress range of 200-260 MPa till failure. The creep curves exhibited shorter primary regime followed by marginal secondary regime and extended tertiary creep regime, in particular at high stress levels of 240-260 MPa. The Sin-Hyperbolic model successfully predicted the sigmoidal bend in creep curves at primary to secondary transition and secondary to tertiary transition at most of the stress levels. Further, the isotropic creep damage formulation in the Novel Sinh model was found to mitigate rapid damage accumulation from the early stages of creep deformation, with damage values reaching to unity or finite value at the rupture. This in turn facilitated successful capturing of the prolonged tertiary creep stage in IN-RAFM at all stress levels.</div></div>","PeriodicalId":20518,"journal":{"name":"Procedia Structural Integrity","volume":"71 ","pages":"Pages 188-195"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144902544","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 characteristics of erosion in secondary elbows mounted in series, which are common in industrial pipelines, differ from the erosion observed in primary and single elbows. This difference is due to the secondary flows developed in the primary elbow, which influence the motion of particles impacting the secondary elbow. In the present work, computational fluid dynamics (CFD) based modeling, using the Eulerian-Lagrangian approach, is performed to simulate particle motion in a gas stream through a pipeline containing two elbows mounted in series. The particle-wall collision data is then used to predict the erosive wear behavior of the elbows using an available erosion model. The modeling is validated using available experimental data. Furthermore, the effect of the connecting pipe length between the two elbows on the erosion characteristics of the secondary elbow (H-V arrangement) is investigated. Simulations are conducted with connecting pipe lengths equal to three times the pipe diameter (3D), 8D, 16D, 30D, and 50D, for three different velocities and four different particle sizes. It has been found that the erosion of the primary elbow is more compared to the secondary elbow and increases with increase in particle size and velocity. The increase in connecting pipe length increases the erosion of the secondary elbow.</div></div>","PeriodicalId":20518,"journal":{"name":"Procedia Structural Integrity","volume":"71 ","pages":"Pages 241-247"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144902551","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}

In polycrystalline aggregates, the combination of computational homogenization and crystal plasticity has shown promise in simulating the effective properties and capturing such correlations. Our study uses a similar framework to model polycrystals with FCC and BCC crystal structures. The goal is to investigate the plastic deformation behavior of these materials, specifically focusing on the role of Geometrically Necessary Dislocations (GNDs). We employ a phenomenological Crystal Plasticity (CP) model on a cubic Representative Volume Element (RVE). The simulations capture the effect of crystallographic orientations, grain boundaries, and dislocation mechanisms on the deformation of polycrystalline RVE. To account for the complex behavior at grain boundaries, a diffused interface model is proposed. This model homogenizes the deformation behavior within the grain boundary region to capture more effectively the hardening due to dislocation pile-up, providing a more realistic representation of the interaction between grains. Our findings provide insights into the influence of grain boundaries on the overall strain hardening and deformation response of polycrystalline materials.</div></div>","PeriodicalId":20518,"journal":{"name":"Procedia Structural Integrity","volume":"71 ","pages":"Pages 461-468"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144902784","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}
