A constitutive and structural FEM module for simulation of the structural response of Aluminum ships to fire effects and assessment of their residual strength is proposed. This module is intended as part of a larger multiphysics fire simulation platform to address the Navy's need for aluminum ships. The module is based on a viscoplastic material model which was shown to be more accurate and effective than the Dorn-Harmathy Arrhenius type creep model. The module will be validated against experimental data and released as an Abaqus module.
