Summary: A model taking into acount unilateral contact condition, friction and adhesion is presented. In the framework of continuum thermodynamics, the contact zone is considered as a material surface, and the local constitutive laws are derived by choosing two specific surface potentials. The adhesion is characterized by a variable which represents the intensity of adhesion. A quasistatic variational formulation and an incremental formulation are proposed. A numerical method is given to solve the problem. The model is used to simulate an indentation experiment which is conducted to characterize the behaviour of fiber/matrix interfaces in a ceramic composite.
