摘要: Decohesion undergoing large displacements takes place in a wide range of applications. In these problems, interface element formulations for should be used to accurately deal with coupled material and geometrical nonlinearities. The present work proposes consistent derivation new deformation analyses. resulting compact leads an operational formulation that enables the accommodation any order kinematic interpolation constitutive behavior interface. derived has been implemented into finite codes FEAP ABAQUS by means user-defined routines. interplay between nonlinearities is investigated considering two different models (tension cut-off polynomial cohesive zone models) small or continuum. Numerical examples are proposed assess mesh independency demonstrate robustness formulation. A comparison experimental results peeling confirms predictive capabilities
