A new method for constructing digital-strain-field-image from a moire pattern with the help of digital image processing technique is proposed in this paper. The
In this paper, the scattering of elastic waves by a plane interface crack in Layered media is investigated. By Fourier integral transform, the method of transfe
The J-integral as a controlling parameter was applied to the crack growing process in an elastic-plastic state by Hutchinson and Paris[1], and Shih et. al[2]. A
