ME305: Mechanics of Materials
This course covers concepts of stress, strain, and deformation. We will introduce constitutive relationships that couple stress to strain by the material’s properties. We show how normal and shear stresses can emerge by axial loaded, torsional loaded, bending, and pressure, and we demonstrate how the stresses are combined during more complex loadings. We will show how stress can by transformed to identify the magnitudes and directions of principal stresses. Finally, we will introduce the concept of structural stability to describe the buckling of beams under compressive loading.
The goals of this course are:
- To identify and calculate stresses in various engineering structures.
- To determine how mechanical structures deform in response to external loads.
- To understand how stress and strain combine to enable problems with complex loads to be solved.
Syllabus: Fall 2017
The course progresses through the following topics:
- Axial Load
- Beam Bending: Normal Stress
- Beam Bending: Transverse Shear Stress
- Combined Loading
- Stress Transformation
- Beam Deflection
- Beam Buckling
