Mechanics

Experiments and Modeling

Creating advanced designs requires an in-depth knowledge of the mechanical response of the materials. Phenomenological models, while very useful for a particular material, are very limited in scope. Understanding the fundamental mechanisms occurring during the fatigue, fracture, creep and stress-relaxation of a material is needed to be able to push the limits of design. Developing models for materials that account for various loading conditions, aging or development of instabilities requires material data that can only be obtained with novel experimental methods. More details about some of mechanics experiments are provided in the links on this page.
