Research Interests

Our research areas are the mechanical properties of metals, including fatigue and fracture of metals, the high-temperature creep of crystalline solids, and dislocation theory applied to these phenomena. We are developing dislocation-based solutions of the plastic regions around stressed cracks. These solutions rely on dislocation crack tip shielding and dislocation crack extension force conditions. In fact, we believe that complete solutions for crack problems in elastic plastic solids cannot be obtained, except for the most simple problems, without use of the dislocation equations.

In the area of geophysics, we recently developed a theory for the migration of subglacial lakes under ice sheets and earthquake dislocations moving at a transonic velocity on a fault separating rock of sightly different elastic constants.In the area of geophysics, our primary research area is in the theory of the flow of glaciers and ice sheets.

Prof. Weertman has an island in Antarctica named after him.
