In this work is examined the variation-difference method of solving the first basic two-dimensional problem of the theory of plasticity for doubly-connected regions using curvilinear rectangular co-ordinates. This approach makes it possible to investigate the questions of stress concentration when the curvilinear boundaries of this form are present, and to attain definite advantages in the realization of a solution to the problems on a computer.
