Abstract

Anisotropic materials are currently used in a wide variety of advanced engineer- ing applications. The most commonly used anisotropic materials are composites and.crystals. These materials are extensively used in aerospace, civil engineering construc- tion, electronic packaging etc. In recent years, transient wave propagation in anisotropicsolids has received increasing attention due to the relationship of this topic to fundamen- tal studies in the areas of smart structures/materials development and the modellingof ultrasonic non-destructive techniques for defect/flaw characterization in materials.This paper is concerned with the propagation of transient stress pulses in an anisotropicelastic solid. The anisotropy of the solid is presented by conventional orthotropy. Ini- tially, general solutions for transient wave propagation in 2-D problems are derived byusing Laplace-Fourier integral transforms. These general solutions are then used tosolve boundary-value problem corresponding to 2-D stress pulses applied at an arbi- trary location in the medium. Solutions are also presented for stress waves emanatingfrom a sudden fracture at an arbitrary location in the medium. Time history of theapplied stress and the displacement discontinuity is assumed to be arbitrary.
