초록

The boundary element alternating method is applied to two dimensional and axisymmetric racture mechanics problems. Different crack depths are considered with particular emphasis on cracks. Several methods of calculating the stress intensity factor are presented and applied to several practical examples to demonstrate their accuracy.
