A finite element model validated through experimental calibration was integrated with Latin hypercube sampling to generate critical ballistic performance data for steel/SiC/UHMWPE multi-layered armor plates.

The optimized MLP demonstrated superior predictive accuracy and lower training loss relative to SVM and RF counterparts. Subsequent implementation of the NSGA-II algorithm on the MLP model generated a comprehensive Pareto frontier that quantifies inherent design trade-offs, while a knee point identification approach based on the minimum distance selection method facilitated optimal solution selection.

However, its application necessitates extensive experimental and empirical estimation of numerous ply-level strength and toughness parameters, many of which lack standardized testing methods, thereby significantly limiting its practical applicability. To support and potentially complement these experimental efforts, this study introduces a new micromechanical damage model (MDM) designed to characterize the traction-separation behaviour associated with matrix-dominated failure modes. This is achieved through employing a representative volume element (RVE) framework to simulate the damage evolution within the matrix and at the fibre-matrix interfaces under multi-axial stress states by using a cohesive zone model. The resultant traction-separation properties serve as inputs to a CDM model for ply-level finite element (FE) analysis of large-scale FRP laminates. The MDM-informed CDM (MDM-CDM) framework presented in this study demonstrates a predictive capability comparable to conventional CDM models in simulating (a) transverse ply cracking and (b) impact damage in FRP laminates. While the MDM approach introduces a distinct set of material parameters—some of which warrant further experimental validation—it offers a physically grounded and computationally efficient means of informing CDM inputs that are otherwise inaccessible through current testing methods.

However, these sensors face challenges in practical applications, including difficulty in balancing sensitivity and measurement range, low self-healing efficiency, and insufficient surface adaptability. To mitigate these challenges, this paper proposes a multi-modulus gradient structured, self-healing, recyclable, and self-adhesive capacitive flexible pressure sensor (MSRS-CFPS). The proposed sensor consists of liquid metal (LM) electrodes and a dielectric layer made up of three integrated self-healing polydimethylsiloxane elastomers (SPE) with different moduli, achieving a balance between high sensitivity (0.061 kPa<sup>−1</sup>) and wide measurement range (65.03 kPa). The MSRS-CFPS demonstrates excellent mechanical healing efficiency (98.85 % MHE) and electrical healing efficiency (99.82 % EHE), which are achieved thanks to the excellent self-healing ability of SPEs and LM electrodes. The sensor can tightly adhere to various complex surfaces without additional fixing devices, and the SPE's elastic modulus can recover up to 91.64 % of its initial value after recycling. The MSRS-CFPS shows a high potential for applications in human motion detection and regional stress measurement.</div></div>","PeriodicalId":10660,"journal":{"name":"Composites Part B: Engineering","volume":"307 ","pages":"Article 112976"},"PeriodicalIF":14.2,"publicationDate":"2025-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144904140","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To achieve a multi-stimulus responsive actuation mode, the soft composite material LCE-CNT/MRF/Ecoflex (LCME) is developed by assembling liquid crystal elastomer (LCE) containing carbon nanotubes (CNTs), magnetorheological fluid (MRF) and Ecoflex. Among them, the additive-free high-performance MRF is prepared by mixing ionic liquid and silicone oil as carrier liquid, and provides magnetic actuation characteristic for LCME. The LCE is a mesh structure material formed by embedding mesogens into elastic polymers and moderate cross-linking them, possessing both soft elasticity and thermotropic shape memory properties. Assisted by the photothermal effect of CNTs, the rising temperature induces the rearrangement of mesogens in LCE containing CNTs (LC), allowing the LC to achieve reversible bidirectional deformation between an initial configuration and a thermotropic configuration. Under the multi-excitation actuation of photothermal effect and magnetic field, the LCME can perform bidirectional crawling and in-situ steering on a plane.
