摘要
求解板壳非线性问题以往常用近似方法 ,但解的精度不高 ,求解过程繁琐 .笔者在前期研究的基础上 ,以四边固支扁壳为例说明了解法导出步骤 ,归纳总结出了求解板壳非线性问题的解析 -数值方法 .实算表明 ,该法对求解板壳非线性问题极为有效 .
An approximate method for solving the non linear displacement of orthotropic plates and shells has been apllied so far.This method can't obtain precise solution and its solving process is havey and complicated.An Analytic numerical method for solving rectanyular plates and shells with large deflection displacement is presented and a solution for four sides fixed supported shallow shell is summed up.Calculation exercises show that this method is very efficient to solve the guestion of the plates and shells with large displacement.
