Nonlinear Crack Analysis with Finite Elements.
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.
