Abstract: This paper presents a summary of the features, verification test results, and important findings of a model developed with the objective of improving the capability for predicting thermal ice forces. The model contains separate of thermal and mechanical components. The thermal analysis is performed using the finite difference method. The mechanical part is conducted using the finite element method and incorporates a non-linear constitutive law for ice, temperature dependent material properties, variable properties through the thickness, cracking, and a variety of boundary conditions. The model is verified by simulations of uniaxial and bi-axial laboratory tests as well as some thermal events for which field data were available. The model was also used to investigate the various factors that affect the thermal ice pressure. Some of the important results obtained in this investigation are presented.
