A finite element formulation of muscle contraction

摘要: The ability to contract is a unique feature of muscular material, as compared technical materials. contractile stress generated by muscle cells, acts along the fibre direction, and has been shown depend on time, elapsed since activation cell, strain rate. In this paper we combine equation conservation momentum with an existing description constitutive behaviour myocardial tissue convert resulting equations into numerical formulation, which implemented in DIANA. Results simulations several contraction experiments are shown.
