利用修正迭代法研究了扁球壳在集中荷载和温度场联合作用下的非线性屈曲问题,得到了临界荷载的二次近似解析公式,讨论了温度场对临界荷载和临界几何参数的影响.
The nonlinear buckling of shallow spherical shell under concentrated load and temperature filed is studied by the modified iteration method, and the analytic formulas for determining the critical buckling load is obtained. The effect of temperature field on critical buckling load and critical geometrical parameter are discussed.
