Typical nanomechanical applications include measuring elastic modulus, friction and adhesion. Viscoelastic materials, which include polymers and biological materials, have elastic properties that ...

We present a constitutive model capturing some of the experimentally observed features of soft biological tissues: nonlinear viscoelasticity, nonlinear elastic anisotropy, and nonlinear viscous ...

Many polymers also have special surface treatments or are applied in form of surface coatings and paints. Instrumented indentation has successfully been applied for various types of measurements in ...

Researchers have created a nonlinear viscoelastic–plastic (NVEP) creep model that accurately predicts how mined ground continues to settle over time. By integrating genetic algorithms and FLAC3D ...

Hysitron nanoDMA III from Bruker is the latest powerful dynamic testing method to perform nanoscale mechanical property measurements. nanoDMA III is fitted with the recently developed CMX control ...

We propose a mathematical model for relaxation modulus and its numerical solution. The model formula is extended from sigmoidal function considering nonlinear strain hardening. Its physical meaning ...

Quantitative characterization of nanomechanical properties has invariably been a holy grail for atomic force microscopy. This article explains some of the industry’s earlier attempts made at ...
