Abstract:

The paper is concerned with the use of finite element methods to provide a reasonably accurate and realistic analytic representation of the nonlinear behavior of arbitrary two dimensional bodies containing cracks. Specific methods are proposed that would provide capabilities necessary to obtain information concerning An accurate description of the maximum, minimum, and residual near-tip stress and strain fields The effects of crack closure on the near-tip behavior of the stress and strain field during cyclic loading into the plastic range The stress-strain and displacement field behavior associated with a nonstationary crack and the effects of large rotation near the crack-tip.
