Sažetak
Due to their specific properties composite materials are being used in a variety of structures. Modern underwater vehicles are a good example: they are light, sturdy and corrosion resistant. Demands posed on such a structures are good sailing properties, good maneuverability and the ability to withstand designed pressure. Nonlinear finite element method (NFEM) is a sophisticated engineering tool that may be used to estimate limitations in the composite-made submersible design. However, the application of the method is not always straightforward. Commercially available NFEM software provides a number of material models but their application is limited by the available material properties. In addition, numerical problems may occur and both material model and numerical model must be verified against instabilities. A particular submersible is being modeled and subjected to NFEM analysis. The overview of commercial software material models is given and their application in structural analysis of a submersible is evaluated. Comparison is made between different structural materials in order to check the submersible maximum diving depth. Numerical problems are commented, different material solutions compared and structure enhancements proposed.
