Submarine Structural Analysis (A012)

The submarine structural analysis capability within Paramarine enables the designer to analyse the structure of axisymmetric submarine pressure hulls by using classical analyses as follows:

• Elastic interframe and overall buckling collapse
• Longitudinal yield failure
• Elastoplastic overall collapse
• Stiffener tripping
• Dome collapse

The analysis available consist of two parts, firstly the classical analysis of axisymmetric submarine pressure hull strength according to methodologies developed by the UK Ministry of Defence over many years.

Additionally Paramarine is able to optimise (minimised weight for a given deep diving depth requirement) a submarine's pressure hull structure using the same classical analysis methodologies as the pressure hull strength assessment. Paramarine will indicate the optimum plating thickness for each segment, together with optimum frame geometries for conical and cylindrical segments for a set of user-defined factors of safety.
