三维等参杂交元的优化设计

OPTIMIZING DESIGN OF THREE-DIMENSIONAL ISOPARAMETRIC HYBRID FINIE ELEMENTS

  • 摘要: 本文将杂交元优化设计原理推广到三维问题,推导了三维等参应力杂交元的优化应力模式,给出了一个具有显式表达的18β等参应力杂交元,并与Atluri等人的结果进行了数值比较。

     

    Abstract: The conceptien ot optimum design for hybrid stress elements is extended to 3-D problems in thin this paper,The optimal formulas of three-dimensional isoparametrie hybsid tress element are derived, and explicitstress patterns with 18β are offered. Saveral numerical examples are given and a comparison is made with the reeults of Atlusi et al.
