利用力学子单元模型和三维20节点杂交应力/混合元对均匀内压作用下的厚壁球壳进行了弹—粘塑性分析。研究了实施中的某些特点。侧重探索了用IBM-PC/XT级微机进行此类问题分析的可能性。数值计算结果与位移元计算结果进行了比较,显示了新方法的优越性。全部计算工作是在IBM—PC/XT微机上完成的。
The elastic-viscoplastic analysis of thick-walled spherical shells subjected to uniform internal pressure was carried out using the mechanics subunit model and three-dimensional 20-node hybrid stress/mixing element. Some characteristics of the implementation were studied. Focused on exploring the possibility of using IBM-PC/XT-class microcomputers to analyze such problems. The numerical calculation results are compared with the displacement element calculation results, showing the superiority of the new method. All calculations were done on an IBM-PC/XT microcomputer.
