摘要: Abstract Transient dynamic fracture mechanics problems are studied using an advanced two-dimensional formulation of the time-domain boundary element method. This employs a set well-behaved kernel functions, which have been used recently for solution general transient elastodynamics. These kernels produce very stable results with respect to both time step and size variations consequently, ideally suited studies. In present implementation, ordinary quarter-point traction-singular elements developed. The stress intensity factors (DSIF) then obtained from crack opening displacements (COD) as well crack-tip nodal tractions elements. A number example investigated in detail. Included convergence studies, comparisons previously published results, evaluation various methods available computing DSIF.
