Dynamic Analysis of Head-Form Test on Actual Automotive Windscreen

摘要

The head-form teston actual automotive windscreenwith the analytic method of explicit dynamics is researched in this paper. Based on the experimentspecification, the geometric models of head-form weight and laminated glass for actual automotive windscreenare built, and the loading conditions of the head-formtestare also acquired. According to the analysis results,the process of crack initiation&propagation and the failure mechanism in laminated glass are studied, which is of great significance for the evaluation on laminated glass for actual automotive windscreen.
