| Abstract: | Based on
the complex function elastic theory, fracture mechanics theory and displacement
variational principle, this paper deduces an approximation algorithm for stress-intensity
factors. The stress-intensity factor is computed for an arch specimen with a crack. The
results indicate that this approximation algorithm is convenient and reliable to the
engineering applications. |
