DYNAMIC-RESPONSE OF CANTILEVERED THIN-WALLED-BEAMS TO BLAST AND SONIC-BOOM LOADINGS

The paper deals with the dynamic response of anisotropic cantilevered thin-walled beams exposed to blast and sonic boom loadings. The struct ural model used in this study incorporates a number of nonclassical ef fects such as transverse shear and warping inhibition. Moreover, imple mentation of a specific ply-angle scheme in each constituent lamina re sults in elastic cross-couplings beneficial from the response behavior point of view. The influence of these effects is highlighted and the efficiency of the tailoring technique toward enhancing the dynamic res ponse to various overpressure signatures is demonstrated.
