## Abstract

The transient response of a central crack in an orthotropic strip under the in-plane shear impact loading is studied by using the dual integral equation method proposed by Copson and Sih. The general formula for the shear stress intensity factor$$\tilde K_{II} (t)$$ near the crack tip is derived. Numerical results of$$\tilde K_{II} (T)$$ with$$T \equiv \frac{{c_s t}}{a}$$ in various cases are obtained by solving the second kind Fredholm integral equation and by performing the inverse Laplace transform.
