We consider the problem of frictional contact between an piezoelectric body and a
conductive foundation. The electro-elastic constitutive law is assumed to be nonlinear and
the contact is modelled with the Signorini condition, nonlocal Coulomb friction law and a
regularized electrical conductivity condition. The existence of a unique weak solution of
the model is established. The finite elements approximation for the problem is presented,
and error...
We consider two static problems which describe the contact between a piezoelectric body and an obstacle, the so-called foundation. The constitutive relation of the material is assumed to be electro-elastic and involves the nonlinear elastic constitutive Hencky's law. In the first problem, the contact is assumed to be frictionless, and the foundation is nonconductive, while in the second it is supposed to be frictional, and the foundation is electrically conductive. The contact is modeled with the...
