摘要
本文利用分支理论和打靶法系统地研究了由两种不同材料组合而成的环形板的轴对称弹性失稳.分析和研究了环形板发生屈曲和过屈曲的条件以及相应的过屈曲性态,并数值地研究了各种参数对组合环形板的稳定性的影响.
Axisymetrical elastic instability of eomposited annular plates made oftwo different materials is studied systematically by means of bifurcationtheory and shooting method in this paper.Buckling conditions and post-buckling behaviours are analysed and the effect of various parameters onthe instability of composited annular plates is investigated numerically.
