| Abstract: | The problem of bimaterial bodies with a crack along the interface may often be met in design of engineering structures and the research of mix-criterion for bimaterial crack is very important. In this paper, a numerical method is proposed for approaching to the problem of bimaterial
bodies with a crack along the interface-a hybrid-element method. The results of stress intensityfators for the bimaterial three-point bending and fourpoint shear beam speciments are obtained by the (hybrid-element) method. |
