摘要
Recent advances in practical engineering methods for fracture analysis of turbomachinery components are described. A comprehensive set of weight function stress intensity factor (SIF) solutions for elliptical and straight cracks under univariant and bivariant stress gradients has been developed and verified. Specialized SIF solutions have been derived for curved through cracks, cracks at chamfered and angled corners, and cracks under displacement control. Automated fracture models are available to construct fatigue crack growth life contours and critical initial crack size contours for all nodal locations in 2D or 3D finite element models.
