夹层结构冲击损伤剩余性能与损伤修复方法
On Residual Performance and Repair Strategies of Sandwich Structures After Impact Damage
摘要
Abstract
This paper investigates the impact characteristics,damage evolution in residual performance,and the damage repair methods of PET foam sandwich structures through a combination of experimental and numerical approaches.The objective is to clarify the mechanisms of impact-induced deformation and damage,the principles for determining damage tolerance and the fundamental structural repair strategies,thereby providing systematic guidance for the application of PET foam sandwich structures.In addition,the successive orthogonal design optimization method is used to perform discrete multi-objective optimization of the structural repair scheme,and a set of optimal repair parameters is obtained for the sandwich structure.These results provide a valuable reference for the effective repair of PET foam sandwich structures.关键词
