Abstract:

The present thesis addresses the numerical modeling and analysis of the dynamic behavior and failure of composite structures subjected to either underwater shock or impact loading. A general purpose computer code was developed and tested for use on personal computers using both the finite element and boundary element techniques. The code can analyze general three-dimensional solid and shell structures. A wide variety of static and dynamic problems with known solutions are demonstrated to verify the accuracy of the code. This code is then used to model and analyze the dynamic response and failure of an unbalanced sandwich composite structure subjected to impact loading. Finally, the effects of composite layer smearing on the fluid-structure interaction are examined. MM
