Transition from Continuous to Jumping Solutions in 2D Quasi-static Elastic Contact Problems with Coulomb Friction: the Mathematics Underlying the Onset of Brake Squeal

Patrick Ballard, Flaviana Iurlano

We formulate the quasi-static elastic contact problem with Coulomb friction in a very general setting, with possible jumps in time for both the load and the solution. Exploiting id…

Homogenization of friction in a 2D linearly elastic contact problem

Patrick Ballard, Flaviana Iurlano
