This is a required core course for all mechanical engineering undergraduate students. Students initially perform yielding and fatigue failure predictions for general structural elements and then focus on specific mechanical components such as gears, fluid film bearing, rolling element bearings, screws, shafts and springs. Use and interpretation of finite element analyses (FEA) are also introduced. The overall goals are for students to learn to make basic design decisions regarding the suitability of different materials in mechanical components (e.g. steel versus aluminum); and to make basic design decisions regarding the suitability of different components in a mechanical system (e.g. ball bearings versus fluid film bearings).

An senior elective course for undergraduate students on the introducion of the Finite Element Method (FEM). Through this course, students gain knowledge in finite element theory and problem modeling. The mathematical formulation of the method is presented. Problem sets are assigned using hand-calculations and computer programs such as MATLAB. The use of commercial FEM software is introduced.

This is a graduate-level introductory course to the fundamental concepts that are required for the design and applications of biomedical prosthetic devices to work together with living biological. These include basic concept in the mechanics of biological materials (tissue and cell) and of the biomaterials, i.e. those materials which are designed to mimic or replace biological materials. Theory and analytical models will be introduced. They will be complemented by the numerical modeling (finite element method). The recent advances on the experimental biomechanics will also be discussed.

A summer course "Fatigue and Fracture of Materials" at the African University of Science and Technology, Abuja, Nigeria. This course covered the fundamentals of solid mechanics and fracture mechanics. These included basic concepts of stress and strain, fracture mechanics, fatigue of materials and the finite element method. An introduction to the failure analysis was also be presented. The lectures were complemented by lab sessions in which students used commercial finite element code.
