Comprehensive Structural Evaluation

For each load case that is being analyzed, the failure analysis provides a quantified evaluation of the failure modes for each principal structural member. This is one of the most powerful failure evaluation capabilities available to the ship structural engineer, and results in a comprehensive level of information that identifies structural problems associated with events such as buckling. These structural failure evaluations are used by the structural engineer to assess the adequacy or degree of conservatism that is represented by the design. The available structural evaluation methodologies include MAESTRO Evaluation, ALPS/ULSAP, ALPS/HULL (hull girder ultimate strength), ABS High Speed Naval Craft (HSNC) and Offshore Buckling Guide, and US Navy NVR criteria.
A structural evaluation framework in MAESTRO exists so that additional design criteria and class rule checks can be easily implemented as needed. The stiffened panel parameter and load generation capability is modularized so that it can be leveraged with multiple rule sets.
