摘要: Asymptotic behaviour of displacements and stresses in a vicinity the interface crack tip situated on nonideal between two different elastic materials is investigated. The described by special transmission conditions along material bonding. corresponding modelling boundary value problem reduced to singular integral equation with fixed point singularities. It shown from solution that asymptotic displacement near essentially depends model parameters. Some numerical examples are presented discussed respect stress singularity exponent generalized intensity factors.
