These materials are renowned for their lightweight, high specific strength and exceptional energy absorption capacity, making them highly promising for applications in automotive crash protection, vibration damping, aerospace, military equipment, and marine engineering. In this study, aluminum alloy-based syntactic foams were fabricated using hollow ceramic microspheres of three different size ranges (75–125 µm, 125–250 µm, and 250–500 µm), with an approximate volumetric fraction of 60 %. The material response and energy dissipation performance of these syntactic foams under shockwave loading were evaluated using a shock tube apparatus driven by commercially available nail gun cartridges. Under impulsive loading, the syntactic foams exhibited global transient displacement due to elastic deformation, followed by rapid recovery to their original configuration. The inherent damping characteristics of the foams induced free oscillation, with oscillation amplitudes progressively attenuating over time. Experimental data demonstrated that both the size of the ceramic microspheres and the intensity of the impulse load significantly influenced the energy dissipation behavior of the syntactic foams. The primary energy dissipation mechanism was attributed to the initiation and propagation of microcracks within the ceramic microspheres. The number of potential sites for the initiation of these microcracks were found to have a positive influence on the energy dissipation efficiency.</div></div>","PeriodicalId":50318,"journal":{"name":"International Journal of Impact Engineering","volume":"203 ","pages":"Article 105373"},"PeriodicalIF":5.1,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143868293","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}

Conventional methods, such as reducing layup angles or adopting helical structures, often overlook material waste and industrial feasibility. Additionally, hybrid laminate designs are challenged by the absence of robust scientific methods for selecting material proportions and layup angles. To address these challenges, this paper introduces the isotropy degree index (IDI), a novel metric quantifying how closely the in-plane tensile properties of a laminate approximate isotropic behavior. Based on prior studies on the tensile properties of multiaxial warp-knitted fabrics, this paper deduces a method for calculating the IDI and integrates it into the design of impact-resistant laminates. A laminate's impact resistance strongly depends on its in-plane mechanical properties, and the reliability of this approach is demonstrated through experimental tests, finite element analysis, and industrial CT scans. The results demonstrate that increasing the IDI significantly improves impact strength, reduces impact-induced displacement, and promotes symmetrical delamination patterns diminishing toward the laminate edges. Moreover, a higher IDI mitigates through-thickness force propagation, thereby reducing matrix damage. This research underscores the critical role of IDI in optimizing laminate performance, providing practical guidelines for the design of next-generation impact-resistant composite laminates.</div></div>","PeriodicalId":50318,"journal":{"name":"International Journal of Impact Engineering","volume":"203 ","pages":"Article 105343"},"PeriodicalIF":5.1,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143835046","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}

Since stiffened plates are typical structures in ships, studying the impact of underwater explosions with different types of explosives on ships is of great significance. This experiment investigated the damage characteristics of blasting, shaped, and linear shaped charges on the same type of stiffened plate. The experimental results indicate that linear shaped charges can create larger penetration holes on target plates, but they suffer from insufficient flight capability. In contrast, shaped charges exhibit stronger penetrating power, yet they lack sufficient damage capability against target plates. Although the penetration capability of blasting charges is inferior to the first two, its overall deflection of the plate frame exceeds that caused by shaped charges and linear shaped charges by 1.6 % and 5.7 %, respectively. To further investigate the penetration process and the load characteristics of the penetrator, a finite element model was established in this paper.

Increasingly, micrometeoroid and orbital debris (MMOD) pose significant risks to these assets. Carbon fiber reinforced polymers (CFRPs) offer an improved balance of mechanical and physical properties for MMOD shielding and structural components, as they can be customized to specific applications. Assessing the impact of MMOD on CFRP truss members is essential to evaluate their viability for large-scale space structures in future missions. This study focuses on identifying and quantifying the sub-surface damage from MMOD impacts on circular CFRP truss members and measuring the residual strength of individual truss members post-impact. Using high-speed imaging and X-ray computed tomography (XCT), this study quantified the extent of sub-surface delamination and residual strength loss in CFRP truss members impacted by hypervelocity projectiles, while compression after impact (CAI) tests were employed to measure the mechanical degradation caused by such impacts. The results indicate that sub-surface delamination, rather than the size of the hypervelocity impact entry hole, has the strongest correlation to the reduction in strength of the damaged composite truss members.</div></div>","PeriodicalId":50318,"journal":{"name":"International Journal of Impact Engineering","volume":"203 ","pages":"Article 105345"},"PeriodicalIF":5.1,"publicationDate":"2025-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143845084","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}
