RE: New Undergraduate-Level Course

The faculty of the Department of Biomedical Engineering has approved the following new course. This action is now submitted to the Engineering Faculty with a recommendation for approval.

BME 204 Biomechanics of Hard and Soft Tissues

Sem. 2. Class 3, cr. 3.

Prerequisite: ME 270, BIOL 295E, or equivalent

Corequisite: MSE 230 or equivalent

Covers the mechanics of biological materials, with applications in the musculo-skeletal system, nerves, spinal cord, and vascular tissue, down to the level of the cell. Topics include center of mass, moment of inertia, basic understanding of stresses, strains, and deformations, axial elements, pressure vessels, beams, torsion, viscoelasticity, and thermal stress. Case studies and problem solving sessions used to emphasize the unique biological criteria which must be considered when mechanically analyzing both soft and hard tissues.

Reason: This course introduces students to a variety of physiological systems through an understanding of engineering principles, specifically related to mechanical and material properties. Students learn the mechanical properties of biological materials in order to be able to analyze and design replacement systems for biomedical applications.
