摘要
基于弹塑性板壳失稳理论,采用YBT模型和非线性弹塑性有限元分析,以08Al车身钢板和普通低碳钢板为比较对象,通过数值模拟研究了新型Al-Mg-Si合金车身板的皱曲特性。
Based on elastic-plastic thin shell instability th eo ry,this works investigated buckling characteris-tic on new type Al-Mg-Si al loy auto body sheets by means of numerical simulation,adopting YBT and nonlinea r elastic-plastic finite element analysis,comparing with08Al and plain low carbon steel sheet.
