摘要
工程中使用的多数材料实际上拉、压机械性能都是不同的.本文利用不同模量弹性理论,结合有限元法,以位移为参考标准,用迭代法,编制了电算程序.计算了轴对称壳获得了一些有益的结论.
Most engineering materials possess different elastic module for tension and compression. Due to nonlinearity of the different modulus theory of elasticity, limited analytical solutions for simple cases have been obtained. Using numerical methods of FEM combined with iterative algorithm, the authors compile a computer program for 3-D axisymmetric structures of different modulus materials. Through computation of axisymmetric shells, some useful conclusions are drawn.
