This internship investigates the brittle-to-ductile transition (BDT) in amorphous solids using numerical simulations of model colloidal glasses. The project focuses on the “expanding particle” protocol, where particles are gradually inflated to generate glassy states with controlled disorder and density. The goal is to understand how preparation conditions influence the mechanical behavior and yielding of these materials. The work is part of a larger interdisciplinary project involving both theorists and experimentalists, aiming to identify and characterize the emergence of the BDT in real colloidal systems. The student will gain hands-on experience in computational soft matter physics, analyzing structure, local stresses, and microscopic precursors of failure. Continuation as a PhD project is possible for strong candidates.
