| Abstract: | The stress rate integral equations of elastoplaticity are deduced based on Ref. 1] by consistent methods. The point at which
the stresses and/or displacements are calculated can be in the body or on the boundary, and in the plastic region or elastic
one. The existence of the principal value integral in the plastic region is demonstrated strictly, and the theoretical basis
is presented for the paticular solution method by unit initial stress fields. In the present method, programming is easy and
general, and the numerical results are excellent.
