主 题:Adhesive bonded material Interface crackDynamic stress intensity factor Integral transformationSingular integral equation
摘 要:Dynamic fracture behavior of a Griffith crack along the interface of an adhesive bonded material under normal loading is studied. The singular integral equations are obtained by employing integral transformation and introducing dislocation density functions. By adopting Gauss-Jacobi integration formula, the problem is reduced to the solution of algebraic equations, and by collocation dots method. their solutions can be obtained Based on the parametric discussions presented in the paper, the following conclusions can be drawn: (1) Mode I dynamic stress intensity factor (DSIF) increases with increasing initial crack length and decreasing visco-elastic layer thickness, revealing distinct size effect; (2) The influence of the visco-elastic adhesive relaxation time on the DSIF should not be ignored.
