我们通过分析和数值研究了各向同性活性固体的通用连续介质模型，该固体具有由非平衡“活性”机械化学反应产生的内应力。我们的分析表明，可以通过增加运动活动来调节凝胶通过三类动态状态：均匀密度的恒定无应变状态，局部密度表现出持续振荡的状态，以及自发收缩的稳定状态，具有均匀的平均密度。版权所有 (C) EPLA，2011
We study analytically and numerically a generic continuum model of an isotropic active solid with internal stresses generated by nonequilibrium "active" mechano-chemical reactions. Our analysis shows that the gel can be tuned through three classes of dynamical states by increasing motor activity: a constant unstrained state of homogeneous density, a state where the local density exhibits sustained oscillations, and a steady state which is spontaneously contracted, with a uniform mean density.
