Abstract
A theoretical formulation of stress-induced volumetric material growth in thermo\-elastic continua is developed. Material growth is regulated by a three-surface activation criterion and corresponding flow rules. A simple model is proposed based on this formulation and its algorithmic implementation, including a method for solving the underlying differential/algebraic equations for growth, is examined in the context of an implicit finite element method. Selected numerical simulations are presented that showcase the predictive capacity of the model for both soft and hard biomaterials.
