| Course Description: | The application of continuum and microstructural concepts to consideration of the mechanics and mechanisms of flow and fracture in metals, polymers and ceramics. The course includes a review of tensors and elasticity with special emphasis on the effects of symmetry on tensor properties. Then deformation, fracture and degradation (fatigue and wear) are treated, including mapping strategies for understanding the ranges of material properties. | |
| Course Outline: | Intro to mechanical
testing at the macro and micro scale. Review of elasticity and tensors with solutions to some elasticity problems, beams, cracks, dislocations. Analysis of the nanoindentor and the AFM. Irreversible deformation (plasticity), including twinning, martensitic and other dilatant transformation mechanisms. Dislocations, strengthening and deformation properties of crystalline materials. Effects of sample size on dislocation content, dislocation-free nanomaterials. Hall-Petch, precipitates, transformation toughening,… Rate-dependent and high temperature deformation of materials. Fracture of materials. Mechanical properties and optimal materials application - mapping strategies. Materials degradation by mechanical processes, fatigue and wear. |
