Plasticity

a possible seminar on friction as fracture

Submitted by Mike Ciavarella on Fri, 10/30/2026 - 20:16

Dear colleague,

I am preparing a seminar that I will give at several universities, and I would be glad to offer it to your group as well, either online or, if you are able to invite me, in person.

The seminar is about recent theories of friction and frictional contact, viewed as a fracture problem. In the "Griffith friction" picture the edge of the stick zone is treated as a shear crack, and this explains why static friction depends on load, size and roughness. It covers:

Open Postdoc position for Fall 2023 on computational methods to process experimental data

Submitted by Andrew J. Gross on Tue, 07/04/2023 - 04:08

uncertainty quantification

One postdoc is sought to fill an opening in the Gross Materials Lab (group website: andrewjgross.com) at the University of South Carolina. This research is focused on extracting yield surfaces from data rich full-field experimental information by solving an inverse problem. This research will be primarily computational and will integrate closely with a graduate student conducting experiments. Applicants with relevant experience are strongly encouraged to apply.

A Geometric Field Theory of Dislocation Mechanics

dislocation mechanics

continuum dislocation dynamics

In this paper a geometric field theory of dislocation dynamics and finite plasticity in single crystals is formulated. Starting from the multiplicative decomposition of the deformation gradient into elastic and plastic parts, we use Cartan's moving frames to describe the distorted lattice structure via differential 1-forms. In this theory the primary fields are the dislocation fields, defined as a collection of differential 2-forms. The defect content of the lattice structure is then determined by the superposition of the dislocation fields.
