双材料界面应力分析的局部杂交法

THE STRESS ANALYSIS OF THE INTERFACE OF BIMATERIALBY A LOCAL HYBRID METHOD

摘要: 本文用云纹干涉法测取双材料高梁受集中载荷时沿ｘ，ｙ轴的位移场ｕ，ｖ．以其作为界面局部微区的边界条件，用有限元计算此微区内界面上的应力分量．与光弹性及全梁有限元法比较，发现局部杂交法的精度最高．

Abstract: In this paper, the local hybrid method, combining he moire interferometry experiment with FEM, is used to evaluate the experimental results in interfacal region. The results of local hybrid method is compared with photoelasticity and FEM method.
