汽车涂层样本单颗粒冲击破坏仿真分析
Simulation Analysis of Single-Particle Impact Damage in Automotive Coating Samples
摘要
Abstract
Studying the impact-induced failure phenomenon of automotive coatings is of great significance for predicting damage and guiding the structural design and optimization of the coatings.A finite element model for the single-particle impact failure of automotive coating samples is established,and this model is solved by using an in-house explicit finite element solver,FTW-GPU.The predicted failure patterns of in-ply failure and interface delamination of the automotive coatings are in good agreement with the experimental outcomes,which verifies the effectiveness of this numerical method and reveals the failure mechanisms of in-ply failure and interface delamination in coatings under impact load.关键词
