The Time-Averaged Elastodynamic J-Integral
Source abstract
Abstract
The time-averaged path independent J-integral for a stationary crack subjected to time-harmonic elastic waves is introduced. It can be determined from remote fields providing an alternative approach to compute the stress intensity factors. The J-integral is evaluated for a semi-infinite crack impinged by a plane sheer wave at an oblique angle.
