Abstract

This chapter discusses a phenomenological approach to simulate active contraction within the framework of elasticity theory. The concepts of an evolving zero-stress configuration and time-varying elasticity are introduced. These ideas are used to model the fundamental behavior of contractile structures. The theory is then used to study the mechanics of the beating heart.
