蠕动固体的定期训练
Periodic training of creeping solids
摘要：
我们考虑无序固体，其中的微观元素可以塑性变形，以响应对他们的压力。我们表明，通过定期驱动系统，这种可塑性可以利用训练在所需的弹性性能，无论是在全球的模量和当地的“变构”的相互作用。周期性驱动可以将施加的“源”应变耦合到能量景观中的路径上的目标应变。这种耦合允许控制系统的响应，即使在大应变良好的非线性制度，它可能难以实现简单的控制设计。
英文摘要：
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.
