This Course:
- Describe how the tension test is used to plot the stress-strain curve of a material.
- Identify the elastic limit, proportional limit, yield point, and ultimate stress on a stress-strain plot.
- Explain the difference between the elastic limit, the proportional limit, and the yield point.
- Characterize material behavior by referring to elasticity, inelasticity, plasticity, yielding, strain hardening, permanent deformation (permanent set), and necking.
- Compute the modulus of elasticity for a material with a well-defined elastic zone.
- Use the 0.2% offset method to determine an approximate yield stress.
- Explain the difference between brittleness and ductility by referring to the stress-strain curve.
- Explain the advantage of ductility in engineering.
- Compare different materials and rank them in terms of strength, stiffness, and ductility.
- Contrast behavior when a material is unloaded in the elastic range versus the plastic range.
- Recognize that in engineering practice, the proportional limit, elastic limit, and yield stress are close in value are are often lumped together and called the yield point.
