Variational analysis of a frictional contact problem with wear and damage
Mathematical Modelling and Analysis, 2021 We study a quasistatic problem describing the contact with friction and wear between a piezoelectric body and a moving foundation. The material is modeled by an electro-viscoelastic constitutive law with long memory and damage.

A Constitutive Friction Law for Sheet-Bulk Metal Forming
Tribology Online, 2016 Friction has a significant effect on metal forming both in economic and technical terms. This is especially true for sheet-bulk metal forming, which is a combination of bulk metal forming and sheet metal forming.
