The interactions between two materials contacted are important for stability of engineering projects. Based on the actual stress state of two contacted materials
uni-body and bi-body models are employed to study the phenomenon. Through analyzing the test results
we conclude that uni-body model can be considered as bi-body model under certain conditions. In addition
the parameters which affect the two models are also analyzed. There are two important parameters that affect the mechanical performance of uni-body model
one is the strength ratio k between two materials; and other is the cohesion c of contact surface. Apart from the main parameter k
fracture toughness ratio ?
volume ratio ? and the surface roughness are influence factors for the mechanical behaviors of bi-body model
