Problem of Two Exterior Griffith Cracks opened by heated wedge in a strip whose edges are normal to crack axis

As we know structures behave in different fashion under climate variation and the most responsible for these variations is heat which falls through and causes deformation of the body. The present paper deals with the problem of two exterior Griffith cracks opened by heated wedge in a strip whose edges are normal to crack axis and the medium is assumed to be homogen and isotrop. Under plain strain condition the closed form expressions for physical quantities such as normal stress components, stress intensity factors and the crack shape are obtained by using the Fourier sine and cosine transformation.
