Engineering Mechanics (E MCH)

E MCH 535 (MATSE 564) Deformation Mechanisms in Materials (3) Deformation of crystalline/amorphous solids and relationship to structure; elastic, viscoelastic and plastic response over a range of temeratures and strain rates.

E MCH 535 (MATSE 564) Deformation Mechanisms in Materials (3)

The course will study the relationship between the deformation mechanisms in materials and their structure.  The types of deformation behavior considered in the course are linear elasticity (isotropic or anisotropic), viscoelasticity and plastic deformation.  For the elastic behavior, the emphasis will be on the way elastic behavior is controlled by atomic structure and microstructure.  The constitutive laws that describe this behavior and the assumptions on which they are based will be introduced.  The next phase of the course considers the range of deformation behavior from purely viscous (linear or non-linear) to viscoelastic.  Initially, the emphasis will be on the effects of temperature and strain history and the way this behavior is described by mechanical analogs.  The effect of structure on creep and stress relaxation will be described.  The use of linear viscoelasticity in describing the sintering process will also be included.  In ductile crystalline materials, deformation is associated with the movement of dislocations.  The types of dislocations, their stress fields and energies will be described.  These aspects will then be combined with structural features by including considerations of slip geometry and obstacles to dislocation motion.  This approach will allow strengthening methods to be identified and quantified.  Finally, creep mechanisms in crystalline materials at high temperature will be discussed and quantified.
