The cyclic torsion test was carried out by tubular butt-joint with highly ductile acrylic adhesive, and it was investigated the relation between shear stress and shear strain with various experimental conditions. In addition, the shear stress-strain constitutive equation was considered. And the constitutive equation was incorporated into the user subroutine of a general purpose finite element analysis program. Subsequently, the experiments and analysis of the stretch-bending/unbending and die-bending for adhesively bonded sheet metals were performed.

采用高韧性丙烯酸酯胶粘剂对圆管对接接头进行了循环扭转试验，研究了不同试验条件下剪切应力与剪切应变的关系。此外，考虑了剪切应力-应变本构方程。并将本构方程编入通用有限元分析程序的用户子程序中。随后，对复合板的拉弯/放弯和模具弯曲进行了实验和分析。
