We consider disordered solids in which the microscopic elements can deform plastically in response to stresses on them. We show that by driving the system periodically, this plasticity can be exploited to train in desired elastic properties, both in the global moduli and in local “allosteric” interactions. Periodic driving can couple an applied “source” strain to a “target” strain over a path in the energy landscape. This coupling allows control of the system’s response, even at large strains well into the nonlinear regime, where it can be difficult to achieve control simply by design.

定期训练蠕变固体[物理]

我们考虑了无序的固体，其中的微观元素可以响应其上的应力而塑性变形。我们表明，通过周期性地驱动系统，可以利用这种可塑性在整体模量和局部“变构”相互作用中训练所需的弹性。周期性驱动可以将施加的“源”应变耦合到能源格局中路径上的“目标”应变。这种耦合允许控制系统的响应，即使在很大的应变进入非线性状态时，也很难通过设计来实现控制。
