ABSTRACT. The mechanical behavior of materials is temperature dependent. The unique thermal failure phenomenon known as heat explosion is a result of a specific combination of material properties and temperatures. The goal for this paper is to revisit a specific previously created model, and improve it by performing a sensitivity analysis on the input parameters to determine which parameter affects the occurrence of heat explosion the most. This is done by computational analysis of thermoviscoelastic parameters to determine how the critical values at which heat explosion occurs are affected by different inputs. Then, that data was used to perform a sensitivity analysis through the use of partial derivatives and vector field to determine which parameter had the highest degree of effect on the critical values. The results of this research make modeling heat explosion more realistic, and designing for it easier.
