Mechanics of Materials

Lesson 07

Thermal Effects

Learning outcomes

This Course:
    1. Explain what happens to solid materials when they are heated or cooled.
    2. State the material property related to thermal expansion (and contraction) and explain its units.
    3. Explain the difference between volumetric thermal and linear thermal deformations.
    4. Compute thermal stress, strain, and deformation for constrained and unconstrained structures.

What happens when you heat up a solid with holes in it? Do the holes get smaller or larger? 

The trick is to think about the material fiber that circumscribes the hole.
