The hardness of a material is defined as its resistance to another material penetrating its surface and is related to its wear resistance and strength. Higher hardness is related generally related to ...

A material’s hardness relates to its mechanical resistance when subjected to mechanical indentation by another harder body. Diamond is considered the hardest natural material and is typically used for ...

In a number of materials, the plastic stress that can be sustained depends on strain rate through a power-law relationship: higher stresses are sustained with higher strain rates and vice versa. In a ...
