有源装药均匀化对弹塑性的增强作用

Enhancement of elasto-dielectrics by homogenization of active charges

Gilles A. Francfort, Antoine Gloria, Oscar Lopez-Pamies

摘要:

我们研究了弹性体中均匀机电耦合的PDE系统。假设一个周期性的微结构和一个预定顺序的微电荷的周期性分布,我们推导出均匀化系统。结果主要取决于周期性(或足够的随机性)和所考虑的微结构类型。我们还表明,如果仔细定制的均匀化电场和明确的增强,以及相应的电致伸缩增强在稀制度的电荷的电增强。

英文摘要:

We investigate the PDE system resulting from even electromechanical coupling in elastomers. Assuming a periodic microstructure and a periodic distribution of micro-charges of a prescribed order, we derive the homogenized system. The results depend crucially on periodicity (or adequate randomness) and on the type of microstructure under consideration. We also show electric enhancement if the charges are carefully tailored to the homogenized electric field and explicit that enhancement, as well as the corresponding electrostrictive enhancement in a dilute regime.
