英文摘要The uniaxial creep properties, including the creep coefficient and stress exponent, are crucial to characterize the creep behavior of materials. Instrumented sharp indentation test (ISIT) is a non-destructive technique to characterize the uniaxial creep properties using the stress equivalent factor and strain rate equivalent factor. However, the strain hardening exponent of tested material is ignored in the contact model, leading to inaccurate estimation of uniaxial creep coefficient. Based on finite element simulations, the effects of the strain hardening exponent on equivalent factors were investigated. The relationships between the equivalent factors, the strain hardening exponent, and the yield strain were established. Indentation and uniaxial tests on Pb95Sn5 and Sn99Cu1 were conducted to validate the established equivalent factors. Then those factors were used to determine the uniaxial creep coefficient of Pb95Sn5 and Sn99Cu1 by ISIT. This work demonstrates the feasibility of measuring uniaxial creep properties of work hardened material by ISIT.
