Abstract

A new analytical method for solving stable crack propagation problems is presented for estimating the maximum load carrying capacity of a ductile panel with a row of cracks. The elastic plastic finite element alternating method was extended to account for the propagating cracks. The crack propagation algorithm utilizes the analytic crack solution to release the stress behind the growing crack tip. The T*ε integral is employed for the crack extension criterion and accounts for the near tip crack growth energy dissipation. A series of analysis have been conducted and the predicted results compare favorably to experimental results.
