DYNAMIC-RESPONSE OF SHORT CURVED PIPES TO IMPULSIVE LOADING

The linear elastic dynamic response of isotropic short curved pipes su bjected to impulsive loading is considered. A series solution based on the Mushtari-Vlasov-Donnell (MVD) shell theory is derived in toroidal coordinates for a comparisons with the Sanders theory for static load ing. The response of pipes is then found for impulsive loading, consis ting of a single pad of uniformly distributed normal pressure acting o n the shell surface. Sample results are given for short curved (toroid al) pipes with loadings applied at the extrados and at the intrados. T hese results are compared with results for corresponding straight (cyl indrical) pipes.
