Discretization of the plane problem for a cracked body with nonlinear stress-strain diagram under tension.

The plane problem for a cracked body with a piecewise-linear stress-strain diagram under tension is reduced by the Fourier transformation to a system of nonlinear algebraic equations. The system is numerically solved for plane strain and stress states of a perfect elastoplastic material to study plastic zones, stress and strain distributions, and displacements of crack faces [ABSTRACT FROM AUTHOR]
