Abstract |
|
We have considered a semiinfinite crack moving with constant velocity in an orthotropic strip with shear-free boundaries. The crack is propagating subjected to constant normal displacements applied at the boundaries of the strip. The Fourier transformation is applied to convert the boundary value problem into the standard Wiener–Hopf equation. This equation has been solved to find out the analytical expressions for the stress intensity factor and crack-opening displacement. The graphs of stress intensity factor and crack-opening displacement have been plotted against various parameters such as crack velocity, strip width etc. to show the effects of these parameters and material orthotropy on stress intensity factor and crack-opening displacement. |
