      Model Recommendation: From a material definition standpoint, it is suggested to use the viscoelasticity material model to capture the temperature dependent relaxation of the elastic modulus under the heat load. Since it is glass, one might be able to use the TN shift function to capture the relationship between time and temperature through the glass transition temperature. Besides, it is suggested to run the model as a full transient dynamic analysis, with appropriate levels of system damping.
