   ABSTRACT: In the first part of this talk, I will recall the notion of
   quasi-static evolution (or rate-independent dissipative process)
   focusing on the simple model of a point mass subject to dry (or
   contact), and then describe the standard approach to existence results
   by time-discretization. In the second part, I will show how the
   hysteresis of contact angle of a capillary drop sitting on a solid
   surface can be modelled by introducing a simple frictional force on the
   contact line. If time permits, I will describe the existence result for
   the corresponding quasi-static evolution. This is a joint work with
   Antonio De Simone (SISSA).
