Exploring fluidization in two dimensional deformable soft matter

Soft amorphous solids are everywhere around us in various forms (colloids, gels, foams, livings cells etc.). In many of these solids, quite often, the constituent particles can change their size or shape. In this thesis, we explore the fluidization of two dimensional models of such soft deformable soft materials. The different questions that we explore are: (i) what are the mechanical properties of a system of particles with active size deformation ? (ii) what happens when a collection of flexible soft objects undergo compression ? (iii) how do glassy systems of rigid or flexible objects differ in their yielding behaviour. Using extensive numerical simulations, we provide physical insights into these different phenomena, from a microscopic perspective.
