Govindjee和Miehe(comp.)发展了一个广义变分公式，它包括任意多个马氏体变异体在单晶情况下的准凸化。冰毒。APPL机甲。英语。2001；191(3-5)：215-238)，并由Stein和Zwickert(Comput.机甲。2006年；正在印刷中)。本文将这项工作推广到具有单调超弹性应力-应变函数的有限应变运动学，以便解释高达15%的大变形应变。
A generalized variational formulation, including quasi‐convexification of energy wells for arbitrarily many martensitic variants in case of mono‐crystals for linearized strains, was developed by Govindjee and Miehe (Comp. Meth. Appl. Mech. Eng. 2001; 191(3–5):215–238) and computationally extended by Stein and Zwickert (Comput. Mech. 2006; in press). This work is generalized here for finite strain kinematics with monotonous hyperelastic stress–strain functions in order to account for large transformation strains that can reach up to 15%.
