本文的工作由两部分组成，分别试图在建立新的杂交应力单元列式方面和有限元的实际工程应用方面作一些有益的探讨。 - After that in chapter four , a axisymmetric hybrid stress finite element for piezoelectric media is presented on the optimization condition for the coupling of electrical and elasticity . it ' s practicable and rational in the numerical example . in the fifth chapter , we study the p - version hybrid stress fem
本文还研究了基于升阶谱的杂交应力元方法，建立了一系列p 5的高阶杂交应力单元列式，数值计算结果显示采用正确的高斯积分，将使得本方法切实可行，同时兼有升阶谱和杂交元的优势。 - The numerical example shows that if we use the correct guess integral , this method will give right answer . it has good performance for both p - version and hybrid stress fem . last , a hybrid stress finite element with second stress completion is presented , which keeps the virtue of normal hybrid finite element , especially good for incompressble material , because it can avoid the self lock of displacement and instability of stress results
第一部分还首次提出了一个满足二次应力完备的杂交应力单元，它的应力满足二次应力完备，而且通过巧妙的应力插值函数，避免了一般杂交应力元的矩阵求逆过程，而通常这个求逆过程都是很耗时的，这个二次应力完备杂交元保持了一般杂交元的优点，对于不可压缩问题具有较好的性能。 - In chapter two of the first part , we give the new axisymmetric hybrid stress optimization function using the wu - pian - huang optimization theory , modify the former function published by t . h . h . pian , wu changchun etc . through the numerical example it ' s easy to get the conclusion that the new axisymmetric hybrid stress finite element we present in this paper has better precision in the results of displacement and stress
Pian等于1987年提出轴对称杂交应力元的优化列式( opc ) ，本文对该优化方法重新进行了推导，对原轴对称问题的杂交应力元列式进行了修正，得到了一个新的轴对称杂交应力单元，通过算例可以看出，同原文相比，该单元的位移和应力的精确度都有了改善。 - Then we apply the method of incompatible fem and hybrid stress fem into axisymmetric problems of transversely isotropic material . with the penalty equilibrium optimization method , we find a new hybrid stress element special for axisymmetric problems of transversely isotropic material . after several numerical examples , the conclusion is made that the hybrid stress finite element with penalty equilibrium has the best capability among all these elements
本文结合电弹耦合问题的应力杂交元优化条件，第一次提出了电弹耦合问题的轴对称杂交应力元方法，建立了轴对称电弹耦合杂交应力单元列式，得到了一个全新的四节点轴对称电弹耦合杂交应力单元，通过算例可见其实用性和合理性。
