... global approach that considers a mean temperature of fluid film. In addition, the thermoelastic behavior of the lip surface is taken into account with a relationship between Young’s modulus and the mean temperature of the lip surface. It is shown that the local temperature of the contact zone increases...

... a Berkovich tip and single crystal alumina and silica samples, are implemented in the proposed area function yielding estimated values of Young’s modulus. Results were compared with that obtained from Oliver and Pharr technique for deep as well as shallow indentation regimes. The estimates for Young’s modulus...

...S. Ozcan; K. Farhang; P. Filip A novel two-parameter area function for determination of near surface properties of Young’s modulus of elasticity and hardness has shown promise for compensating for the imperfection of the tip-end in an instrumented indentation measurement. This paper provides...

..., 2002) using an inverse analysis of the indentation test, the mechanical behavior of polymers is modeled with Young’s modulus for the elastic part and with the G’sell-Jonas’ law with an exponential strain hardening for the viscoplastic part. The strain hardening coefficient is the main characteristic...

These two material properties are of importance in the calculation of wafer’s theoretical removal rate. Experimental results for the removal rates of the copper film are exhibited to compare...
