異方的に成長する生体組織の構成則モデル化と有限要素法への実装

抄録

This study deals with the computational modeling of growth phenomena typically encountered in biomaterials. Constitutive law of growing hyperelastic material is described as an initial value problem analogous to the finite strain elasto-plasticity theory and is implemented into conventional total Lagrange type finite element methods. Some applications to the living tissue with anisotropic growth are presented. To reproduce the growth phenomena realistically, there is a need for detailed verification between experimental facts and the mathematical growth law.
