Abstract
It is presented a path independent integral formulation for
computation of dynamic T-stresses in a two-dimensional body
with a stationary crack. For solution of the crack problem the
boundary element method is used. The uniqueness of the BEM
formulation of a general crack problem is made by the system of
displacement and traction equations on the outer boundary of
body and the crack surface, respectively. The mutual M-integral
expressed through dynamic j- integrals provides sufficient
information for determining T-stresses on the base of found
relation between the M-integral and T-stresses. The integral
representation of the T-stress is presented in the time-domain
and the Laplace transform-domain too. The boundary layer and
displacement field methods are used to test the accuracy of the
suggested integral method. Numerical results are given for the
rectangular plate with a central crack.
