A note on the impact response of a cracked orthotropic material

An approach involving potential functions is used to simplify the equations of motion for an Orthotropic material to an elementary differential equation whose solution may be used for a wide variety of problems in elastodynamics of Orthotropic materials. Solutions for the dynamic mode I and II stress intensity factors for a Griffith crack in an Orthotropic material are obtained. The new approach allows the stress intensity factors to be determined with a minimal use of integral transforms. The solutions for the stress intensity factors are shown to be the same as those obtained by previous researchers.
