摘要

本文旨在研究矩形贴片增强复合材料在剪切载荷作用下的剪应力传递机制。采用二维剪切滞后模型评估了界面弹性和损伤对贴片层和粘结层内部应力传递的影响。研究了衬底泊松比、片径比、长径比和厚度比对复合材料内部应力分布的影响。结果表明，本文二维模型预测的应力分布解与有限元计算结果吻合较好，表明理论预测与有限元模拟结果吻合较好。

Study of stress transfer in a rectangular patch-reinforced composite with partially unidirectional or bidirectional damage interfaces under shear loading

The paper aims to examine the shear stress transfer mechanisms in rectangular patch-reinforced composites subjected to shear loading. A two-dimensional (2-D) shear-lag model was employed to assess the influence of interface elasticity and damage on the transfer of stress within the patch layer and the adhesive layer. The impact of Poisson's ratio of the substrate and the patch, aspect ratio and thickness ratio on the stress distribution within the composite was also investigated. The results demonstrate a satisfactory agreement between the stress distribution solution predicted by the 2-D model in this study and the finite element (FE) results, indicating a good consistency between theoretical predictions and FE simulations.

期刊介绍： Since 1965, the international journal Acta Mechanica has been among the leading journals in the field of theoretical and applied mechanics. In addition to the classical fields such as elasticity, plasticity, vibrations, rigid body dynamics, hydrodynamics, and gasdynamics, it also gives special attention to recently developed areas such as non-Newtonian fluid dynamics, micro/nano mechanics, smart materials and structures, and issues at the interface of mechanics and materials. The journal further publishes papers in such related fields as rheology, thermodynamics, and electromagnetic interactions with fluids and solids. In addition, articles in applied mathematics dealing with significant mechanics problems are also welcome.
