* [https://en.wikipedia.org/wiki/Ultimate_tensile_strength Tensile strength] measures how much stress can be applied stretching/pulling the material before it fractures.

* The [https://en.wikipedia.org/wiki/Charpy_impact_test Charpy test] measures the amount of energy material can absorb at a high strain rate without fracturing (an impact test).

* The [https://en.wikipedia.org/wiki/Flexural_modulus bending modulus] (flexural modulus) is the ratio of stress to strain--the tendency of a material to resist bending.
