Come on folks, no need to get your panties in a wad.

Compressive strength tests are conducted with a static fixture and usually a hydraulic setup to generate steadily increasing forces while measuring displacement.

Tensile testing is conducted by pulling samples apart. Flexural strength evaluates how the stuff bends under lateral load...

This is a far cry from impact testing at Mach speeds. Hard materials are generally very brittle, which means they don’t stand up well to impact. Consider a diamond for example, it’s referenced as extremely hard (w/o going into the numbers), yet you can smash one into smitherings with a hammer.

Any values for measuring “toughness”(Imapct loading) on concrete like the typical Charpy “V” notch test for metals?
