Therefore, this study established evaluation indicators for wrinkle resistance based on macroscopic morphological characteristics using the Yoshida Buckling test and the finite element method. Furthermore, the influence of material parameters of different metal layers (including elastic modulus <em>E</em>, Poisson ratio <em>μ</em>, strength coefficient <em>K</em>, and hardening index <em>n</em>) on the laminate wrinkle resistance was analyzed.

In addition, orthogonal test methods further reveal the sensitivity of each parameter to wrinkle resistance. The results demonstrate that the material properties of the base layer exhibit higher sensitivity to wrinkling resistance than those of the cladding layer.

A total of 48 full-scale specimens were tested under direct tension using a custom-designed experimental setup, instrumented with high-precision LVDTs and supplemented by Digital Image Correlation (DIC) to capture detailed strain distributions. Key variables included concrete strength (C15 and C30), TRM strip width (50 mm and 100 mm), bonding length (150 mm, 300 mm, 450 mm), number of anchors (1 to 6), and anchor configurations (1-row and 2-row systems). The use of fan-type CFRP anchors embedded with cementitious mortar significantly enhanced the bond performance, increasing both maximum load and energy dissipation capacity. Experimental findings revealed that increasing strip width and bonding length improved stiffness and load capacity, up to an effective bond length threshold. DIC analysis enabled high-resolution strain mapping across the TRM-concrete interface, highlighting the localization of maximum strain near anchorage regions and confirming the mechanical influence of both anchorage density and vertical distribution. On average, anchored specimens exhibited 63 % higher peak load and over 100 % greater energy absorption than their unanchored counterparts. The results demonstrate that anchor usage, configuration, and TRM geometry are critical design parameters governing the efficiency, ductility, and reliability of TRM-concrete systems.

Results indicate that both bottom thickness and undercut values increase with higher material strength and sheet thickness, with minimal influence from edge distance. Insufficient clamping at the edge position results in decreased bottom thickness. All joints show an initial increase and then a decrease in peak loads with the increase in edge distance.

The current work presents a comprehensive failure analysis of SPIF components through detailed experiments, microscopic and fractographic investigation, and finite element (FE) simulations. Frustum cone and pyramid components with different wall angles are formed using SPIF. Comprehensive experiments reveal that frustum cones can be successfully formed up to higher wall angles than frustum pyramids due to plane-strain deformation. Although the varying corner radius (VCR) pyramids can be formed at higher wall angles than the constant corner radius (CCR) pyramids, they tend to fail at different orientations on the same wall angle. FE simulations are performed to correlate the fracture of the components with strain accumulation and sheet thinning. Microscopic examination of the crack regions is performed to gain insight into the components’ damage, crack initiation, and propagation. Damage along circumferential direction is observed in already formed regions due to bending and stretching during previous tool passes. Additionally, in higher wall angles (60° and 50°) VCR pyramids, the damage is observed along the meridional direction, contributing to crack initiation. The crack is primarily initiated for 45° VCR and CCR pyramid due to tensile meridional stresses. Moreover, crack propagation is primarily driven by tensile meridional stresses, but shear also plays a role due to tool movement in all cases.</div></div>","PeriodicalId":11677,"journal":{"name":"Engineering Failure Analysis","volume":"177 ","pages":"Article 109682"},"PeriodicalIF":4.4,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143935568","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}

This paper aims to propose a structural concept for a composite leaf spring for heavy vehicles, which should resist the severe stresses caused by poor road conditions, maintaining the stiffness characteristics required for the design, allowing reduction in composite mass, and offering means to dissipate the energy absorbed by the suspension system. Considering rough road applications, suspension springs are commonly subjected to flexural–torsional forces, which justifies the search for a spring concept with increased resistance to these two types of forces. The concept of a sandwich beam with external layers of composite material and a core of more flexible material is explored in the paper. When the fibers of the composite are oriented longitudinally, the sandwich beam can benefit from the high strength of the composite in this direction when subjected to the non-uniform torsion phenomenon. Finite element models are used to obtain failure loads of different concepts of composite beams, and interaction diagrams are plotted considering different combinations of flexural and torsional loads. A representative model of a suspension spring is considered, where simplified geometric constraints are assigned to analyze the structural performance of the sandwich spring concept.

The velocity and vertical strain responses of the dam induced by bubble pulsation are of the same magnitude as those induced by shock wave, while the acceleration response caused by bubble pulsation is significantly lower. The velocity response law inside the dam body is basically consistent along the elevation. Moreover, as the detonation depth increases, the structural response induced by bubble pulsation is delayed. The response results suggest that detonating in the middle of the reservoir is more unfavorable for the dam.
