This document describes the structural analysis and design of four torpedo models - Tiger fish, White head, Mark, and Atlas. The torpedoes were modeled in FUSION360 and analyzed using ANSYS Workbench. The Tiger fish, White head, Mark, and Atlas models had masses ranging from 1503.5 to 1602.3 kg. A static structural analysis found the Atlas model had the lowest deformation of 0.22257 mm and equivalent stress of 8.0091 MPa, indicating it performed best under the loads analyzed. The document concludes the Atlas model obtained better results compared to the other three models.
