Biological processes, from morphogenesis to tumor invasion, spontaneously generate shear stresses inside living tissue. The mechanisms that govern the transmission of mechanical forces in epithelia and the collective response of the tissue to bulk sh...

Ductile and Brittle Yielding in Thermal and Athermal Amorphous Materials (2020)
Journal Article

We study theoretically the yielding of sheared amorphous materials as a function of increasing levels of initial sample annealing prior to shear, in three widely used constitutive models and three widely studied annealing protocols. In thermal system... Read More about Ductile and Brittle Yielding in Thermal and Athermal Amorphous Materials.
