INVERSE ANALYSIS OF MATERIAL PARAMETERS ν12 AND G12 OF ORTHOTROPIC PLANE ELASTIC PROBLEM

摘要

摘要: 采用边界元法和卡尔曼滤波对正交各向异性平面弹性问题物性值进行反分析,由有限个观测点的位移值反算出材料常数\nu_12和G_12. 算例表明了该方法的有效性.

Abstract: In this paper the boundary element method and Kalmanfilter are used to solve the inverse problem for material parameters oforthotropic plane elastic problem. The constants ν12 and G12 of a material may be found with only several known displacements at someobservation points. The numerical examples show that this method is valid.
