Cowper Symonds Analysis of Low Temperature Steels Sustainable Technology for Polar Ships and Structures

It is known that steel structures exhibit enhanced strength when they experience dynamic loads (e.g.

collisions) versus static loads (e.g. bearing loads). A model for this enhanced strength was created by

Cowper and Symonds in 1957, however it is currently only applicable to room temperatures. It is the

aim of this project to extend the applicability of this model to arctic temperatures so that the design of

ships and offshore structures intended for arctic use may take advantage of this inherent dynamic

strengthening. An additional immediate benefit is that this new data is directly compatible with

popular explicit finite element analysis software (e.g. ANSYS-AUTODYNE, NASTRAN, LS-DYNA),

as they have already incorporated the Cowper-Symonds model.
