ABSTRACT:

This lecture describes the difficulties inherent in simulating temporally multiscale phenomena, and introduces some mathematical

approaches to resolving such difficulties. Situations involving fast and slow physical phenomenon often arise, for example, vibration-induced fatigue

of mechanical structures. Vibration happens at a few cycles per second, whereas fatigue takes place over years. But the phenomena are interlinked —

fatigue affects vibration, whereas vibration causes fatigue. Simulating such situations on a computer poses a unique challenge: the time resolution

required to accurately simulate the fast phenomenon makes the slow phenomenon difficult or impossible to simulate. In this lecture we will see

various methods of overcoming this challenge. We will briefly touch upon applications and show some sample simulations using COMSOL.
