Study of mechanical properties of ferroelectrics metamaterials using computer simulation

ABSTRACT

We carried out the computer simulation of the dependences of mechanical properties of a system consisting of flexible substrate and ferroelectric polymer coating on the degree of bending deformations and on temperature within hybrid discrete-continual model. The substrate is modeled as an elastic medium subjected to the Hooke law. For the description of interaction in the polymer coating, we proposed a discrete model based on Stockmayer potential. We demonstrated that the structural transition from the ordered ferroelectric state into depolarized one occurred with the increase of deformations, and the influence of the surface coating on the properties changes became negligible.
