This study aims to investigate the mechanical properties of in-vacuo chain mail fabric through a combination of experimental and numerical simulation methods. First, three different chain mail fabrics composed of various single-cell particles were produced. Subsequently, different external pressures were applied to the fabric to transform it into a load-bearing structure. Finally, three-point bending tests were conducted on the in-vacuo chain mail fabric, and numerical simulations were performed using the finite element software ABAQUS. The research shows that the apparent bending modulus, peak load, and energy absorption capacity of the in-vacuo chain mail fabric increase with the external pressure. When the external pressure reaches 64.5 kPa, the in-vacuo fabric’s apparent elastic bending modulus, peak load, and energy absorption capacity increase by 6 times, 16 times, and 15 times, respectively. Notably, when the three-dimensional particles is square, the in-vacuo fabric exhibits higher load-bearing capacity. Combining the experimental results and numerical simulation results show that the ”tensile contact” and ”compressive contact” between interlocking particles have a significant impact on the overall mechanical properties of the chain mail fabric.</div></div>","PeriodicalId":281,"journal":{"name":"Composite Structures","volume":"368 ","pages":"Article 119237"},"PeriodicalIF":6.3,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144147444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since macroscopic deformations are evaluated based on measured local strains by limited sensors, the sensor placements play a significant role in ensuring precise and robust shape sensing. In practical applications, inevitable and indistinguishable measurement uncertainties can lead to deviations in measured strain and subsequently result in significant errors or even mistakes during reconstruction. Therefore, it is essential to determine suitable sensor placements that are insensitive to measurement deviations for robust shape sensing. This paper proposes an optimal methodology for sensor placement considering measurement uncertainty with the aim of enhancing accuracy and robustness in shape sensing. We establish a mapping relationship between sensor placement and reconstruction accuracy to develop a sensor placement scheme for precise shape sensing. Additionally, a novel technique is presented for the quantification of multiple uncertainties, such as sensor installation errors and signal noise, based on Sparse Grid Numerical Integration (SGNI). Consequently, analytical equations for reconstruction effectively considering measurement uncertainties are derived. Based on the work mentioned above, the optimization of sensor locations can be performed by considering the influences of multiple measurement uncertainties on reconstruction accuracy and robustness. The effectiveness of all proposed methods is verified through experiments, and the applicability of the proposed method to composite structures is confirmed via a deformation reconstruction simulation of a representative composite material.</div></div>","PeriodicalId":281,"journal":{"name":"Composite Structures","volume":"368 ","pages":"Article 119326"},"PeriodicalIF":6.3,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144147443","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
