Abstract:

In analyzing experiments under impact loading, a dynamic model is needed to solve for the deflections and strains as functions of time. For composites, where shear deformation can be very important, incorporation of the transverse shear terms ?_xz and ?_yz in the solution is necessary for accurate stress analyses. This paper presents an analytical approach based on a load versus time function produced through low velocity impact experimentation based on cylindrical shell panel response.
