摘要: Abstract Interface models which relate tractions to displacement jumps and can be used simulate fracture processes are formulated. The formulation identification of the pursued with particular reference analysis composite delamination. difficulties concerning use interface in numerical analyses discussed. A integration method for constitutive laws is proposed, related consistent tangent modulus derived. An algorithm structural presence softening interfaces makes a local control condition presented.
