The Correction Factor in Elastic Modulus Determining by Indentation

Abstract:

The expression for the correction factor β, improving the accuracy of elastic modules measurement by sphere indentation is determined. It is shown that to determine β it is necessary determine the exponent in the equation of the loading curve, in additional to the previously determined parameters of the indentation load-displacement diagram. The computed exponent value of the unloading curve is given. It is shown that to analyze β can be used the results of finite element study of the sphere indentation in elastic-plastic hardening material.
