THE CALCULATION OF DYNAMIC STRESS INTENSITY FACTOR OF INTERFACE CRACK SUBJECTED TO GRADIENT CIRCLING EXPANDING ANTIPLANE SHEAR LOADINGS

摘要：

The dynamic stress intensity factor of a finite interface crack between double-layer mediums is calculated.The crack surfaces are torn by a couple of gradient circling filling anti-shear loading.Using integral transforms,the Cauchy singular integral equation of dislocation intensity function in the transform fields is obtained.The dynamic stress intensity factor in time-t field is determined by the numerical solution of the equation and numerical inverse technique of Laplace transform.It is found that the high speed can suppress the vibration of dynamic stress intensity factor.
