Strain-Rate Sensitivity of Nickel by Instrumented Indentation

Strain-Rate Sensitivity of Nickel by Instrumented Indentation

Notas de Aplicação

In many 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 uniaxial tensile configuration, this relationship between plastic stress, s, and strain rate, e•, is expressed as


where B* is a constant and m is the strain-rate sensitivity (SRS), which is always greater than or equal to zero. For materials which manifest negligible strain-rate sensitivity, m is near zero, making s a constant. (Sapphire is an example of such a material.) Materials with greater strain-rate sensitivity have greater values of m.
