The impact of a soft contractile body on a hard support is described by fields of short range forces. Besides repulsion these forces are able to describe also friction, damping and adhesion allowing the body to have complex motions which look rather realistic. The contractility is used to make the body look like a living body with some basic locomotion capabilities. The simulated motion, like jumping or crawling, is driven either by a contraction or by the corresponding force. Although only affine motions are allowed, the model arises from a general theory of remodeling in finite elasticity and shows also creep and plastic deformations. The body is made of a viscous incompressible Mooney-Rivlin material.

Abstract
The impact of a soft contractile body on a hard support is described by fields of short range forces. Besides repulsion these forces are able to describe also friction, damping and adhesion allowing the body to have complex motions which look rather realistic. The contractility is used to make the body look like a living body with some basic locomotion capabilities. The simulated motion, like jumping or crawling, is driven either by a contraction or by the corresponding force. Although only affine motions are allowed, the model arises from a general theory of remodeling in finite elasticity and shows also creep and plastic deformations. The body is made of a viscous incompressible Mooney-Rivlin material.Pubblicazioni consigliate
