Boundary-Integral Equation Method for Elastic Fracture Mechanics Analysis.
Abstract
A method has been developed and evaluated for merging two dimensional boundary-integral equation and finite element stress analysis programs. A variational formulation has been obtained which provides an analytical basis for the study of different merging schemes. Extensive numerical results are presented which verify the applicability of the merged analyses to fracture mechanics problems. Numerical and experimental results are presented in the area of fatigue life prediction for gas turbine structures with surface or corner cracks to correlate previously developed three-dimensional fracture mechanics analysis methods.
