Distinguish between single crystals and polycrystalline materials. Understand and apply Bragg's law to simple crystal structure determinations. Distinguish between isotropy and anisotropy, and homogeneity and inhomogeneity in materials. Understand their role in shaping material properties. Develop an qualitative understanding of the role of dislocations in the yielding of crystalline materials.
Mechanical Properties Be able to use the concepts of stress and strain in one dimension.
Understand the tensile test, and be able to derive relevant mechanical parameters from such a test. Understand the stiffness parameters Young's modulus and shear modulus, as well as Poisson's ratio, for small deformations. Comprehend deformation measures for larger deformations. Know how to derive yield points from tensile tests. Be able to describe test curves past the yield point.
