Note:               Students are required to attend class.  All exams are closed book & notes and are given in class at the usual time and place.  Course participants are allowed to bring one hand written sheet (8.5”x11”) of information (both sides).  All three of these written sheets can be saved and brought to the final exam.  The first three in class exams will have both problem solving and multiple-choice questions; the final exam will have only multiple-choice questions.

 

Missing an exam will result in ZERO for that exam unless there is a valid excuse with documentation.  In that case, the scores on subsequent exams will be more heavily weighted.  No make-up exams will be given for any reason whatsoever.  No exams will be given in advance, for any reason whatsoever.  Please do not ask take an exam in advance, or to take a make-up exam. 

 

Homework Assignments will be collected and partially graded. No late assignments will be accepted. Not all problems will be graded.  Solutions will be posted after due date.

2.      Students will be able to solve numerical problems involving steady and unsteady state diffusion in crystalline solids.

3.      Given the stress-strain curve for a material, students will be able to determine the modulus of elasticity, yield strength, tensile strength, and ductility

4.      Students will be able to explain the relationship between a material’s thermal properties and its atomic bonding and three-dimensional structure. 

5.      Students will be able to explain the failure of materials by fracture, fatigue, and creep.

6.      For an equilibrium phase diagram, students will be able to determine the composition and the mass fraction of each phase and each microstructure present.
