Through combined drop-weight impact tests, post-impact residual static tests, and high-fidelity finite element simulations, we demonstrate that SFCB reinforcement significantly enhances structural recoverability and damage control compared to conventional steel rebar, attributable to its stable post-yield stiffness. The self-sensing capability of SFCBs successfully correlates distributed residual strain patterns with structural resilience, enabling effective post-impact assessment. A comprehensive parametric analysis identifies a post-yield stiffness ratio of 0.07 as a critical threshold for optimizing resilience. Furthermore, a quantitative predictive model is established, explicitly linking the restitution coefficient to the equivalent reinforcement ratio and post-yield stiffness ratio, thus providing a vital tool for the performance-based design of impact-resilient structures.

The formation mechanism of penetration tracks has not been fully understood, hindering modeling the correlation between track morphologies and projectile parameters accurately. In this work, a laser-driven microparticle launch system is constructed. The ballistic impact experiments are carried out on low density silica aerogel (80 kg·m<sup>-3</sup>) with spherical projectiles at 100∼900 m·s<sup>-1</sup>. Via in-situ observation, the energy dissipation and track formation mechanism are discussed. Based on the clarified mechanism, an analytical model considering target strength as well as hydrodynamic force is proposed. To further understand the experimental observations and conduct parametric studies, numerical simulations are performed with the JH-2 constitutive model and Kelvin cell. Experimental validation confirms the high reliability of both the simulation and theoretical model. The theoretical model achieves an accuracy of up to 90% across a wide range of impact velocities (from 0.1 to 6 km·s<sup>-1</sup>). The effects of projectile parameters on induced tracks are investigated with the verified models.

Experimental research in the past decade informed design guidance for CLT components against blast loading and forced entry, but formal guidance for CLT systems under ballistic impact is not currently available partly due to inherent uncertainties affecting localized resistance. In this article, we investigate the impact of quasi-static wood material property variability on partial penetration ballistic resistance uncertainty by conducting 61 total ballistic impact experiments on an untested prominent structural species, Douglas Fir (DF). With the DF experimental results in combination with a leveraged CLT ballistic and material property database, we predict and characterize the ballistic resistance of any CLT panel using a defined single penetration depth equation and the computationally inexpensive reliability-based First-Order Second-Moment (FOSM) method. We use this approach to characterize and capture the inherent variability of CLT under ballistic impact, and represent resistance profiles as probabilistic distributions rather than single values. We apply the predictive method at different scales, from DF panel-specific single velocity estimates to full species partial penetration profiles. For each data grouping, the FOSM prediction fully captured within 95% confidence intervals the experimental dataset. Needing only two easily obtained wood material properties, the method provides accurate and robust predictions of the resistance of this variable material under dynamic localized loading. As a result, we argue predicted baseline resistance profiles considering inherent material variability can act as the informed starting point for decision makers to apply situation dependent design safety factors.</div></div>","PeriodicalId":50318,"journal":{"name":"International Journal of Impact Engineering","volume":"211 ","pages":"Article 105617"},"PeriodicalIF":5.1,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145841595","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this issue, this study proposes a load-mitigation strategy based on a Re-entrant Hexagonal (REH) lattice structure. Benefiting from its low weight, high strength, high specific energy absorption, and geometric design flexibility, the proposed lattice effectively attenuates water-entry impact loads. The oblique water-entry load characteristics were first captured using a dedicated cross-medium experimental platform, while the lattice parameters were optimized through a particle swarm optimization–support vector machine (PSO–SVM) algorithm. Subsequently, a finite element model employing an equivalent loading method was developed to elucidate the dynamic response mechanisms, leading to the design of an embedded lattice-based load-mitigation nose cap. Experimental validation demonstrated that the proposed structure achieved a 50.6% reduction in peak load through progressive plastic buckling, multi-hinge formation, and energy dissipation.

This paper presents a novel methodology based on wavefield decoupling in short rock bars and frequency-domain analysis to tackle these issues. By examining the superposition of multiple reflected waves within short rock specimens in the Split Hopkinson Pressure Bar (SHPB) apparatus, the proposed method overcomes the limitations of traditional techniques concerning specimen size and high-strain-rate simulation, while also simplifying experimental complexity.
