What is it about?
Applied stress can accelerate the process of physical aging of polycarbonate in a similar fashion as the elevated temperature does. Thus, the data from loaded aging test in short-term can be used to obtain the long-term aging behaviors of polymer materials without actually conductedlong-time aging test . This approach can dramatically save time and cost since no long-term aging test is needed.

Why is it important?
With the propsed time-temperature-stress superposition principle, the data from loaded aging test in short-term can be used to obtain the long-term aging behaviors of polymer materials without actually conductedlong-time aging test . This approach can dramatically save time and cost since no long-term aging test is needed.
