A method for predicting an elastic modulus of a material includes providing a sample in a dynamic mechanical analysis device, performing a temperature sweep test to obtain a first data set, performing a frequency sweep test to obtain a second data set, using the second data set to generate a master curve in a frequency domain of the at least one of the storage modulus of the sample or the loss modulus of the sample using time-temperature superposition, converting the master curve in the frequency domain into a time domain relaxation function, and using the time domain relaxation function to predict the elastic modulus of the material.
