摘要
研究了对称层合圆柱正交异性扁球壳在温度场和均布压力联合作用下的热屈曲问题.考虑横向剪切的影响,应用修正迭代法获得了温度场影响下的临界荷载的解析表达式,讨论了剪切刚度和温度场对临界荷载的影响.
The nonlinear thermal buclding of symmetrically laminated cylindrically orthotmpic shallow spherical shell under temperature field and uniform pressure including transverse shear is studied by using the modified iteration method. And the analytic formulas for determining the critical budding loads under different temperature fields were obtained. The effect of transverse shear deformtion and different temperature fields on critical buckling loads were discussed in a numerical example.
