Diffraction of P-Waves by Edge Crack in an Infinitely Long Elastic Strip
The in-plane problem relating to the elastodynamic response of edge crack in an infinitely long elastic strip is analyzed. Fourier transform is used to reduce the mixed boundary value problem to Fredholm integral equation of second kind which was solved numerically to calculate the stress intensity factor at the tip of the crack. Stress intensity factor for various geometry parameters and frequency has been plotted to show the effect of strip width on stress intensity factor. Also normal stress at distant points from the crack has been evaluated numerically and plotted for various parameters.
