SIMPLIFIED ANALYSIS OF COMPOSITE CYLINDRICAL SHELLS SUBJECTED TO LOW VELOCITY IMPACT

Under the assumption of the existence of an equivalent column which has the same failure behavior as the composite shells following axial impact, the failure of the shells was reduced to a one dimensional problem. An equivalent law was introduced in this paper. By means of the elastic dynamics theory, a simplified impact load was obtained, and then the dynamic radial displacements of the cylindrical shells were determined.
