Project Description

Hysteretic materials have an analog memory of the past that determines their transient responses to imposed stresses. Their memories allow them to dissipate energy, which is critical to controlling sound and vibration. We investigate the effects of hysteresis using transient simulations of complex dynamic systems with the goals of improving finite element models and discovering optimal damping paradigms.
