Time-dependent mechanical characteristics measured through the use of a microindentation technique
Original language description
Under accepted simplifications about the linear viscoelastic background of the problem and the time-independent value of the Poisson's ratio, this paper aims to compare the short-term histories of the viscoelastic functions of a common time-dependent material, e.g. viscoelastic compliance and relaxation modulus measured using a microindentation technique, with data derived from standard macro measurements. Two nano/microindenters were used (Hysitron Triboscan and Nano XP Indenter) at two different laboratories. Four special time-dependent loading histories were applied: indentation under a step load, indentation under a constant load rate, indentation with a fixed depth of penetration and indentation under constant rate of penetration. The goal of thestudy is to assess the potential of this approach.
