Submarine Certification Is an FEA First

Submarine design typically follows American Bureau of Shipping (ABS) code, which establishes properties such as hull thickness, frame stiffness, porthole and hatch design and so on. ABS wanted to assist designers of a unique, private submarine by predicting performance prior to construction and sea trials. And also they wanted to predict global buckling behavior and local stress concentrations. To master these challenges ABS chose Siemens PLM Software. ABS deployed the preprocessor, Femap software from Siemens PLM Software. Femap gave complete control over the initial geometry so that it could be set up exactly as the analysts needed for an accurate solution.
