An analysis of the elastic properties of a porous aluminium oxide film by means of indentation techniques [PDF]

, 2013
The elastic modulus of thin films can be directly determined by instrumented indentation when the indenter penetration does not exceed a fraction of the film thickness, depending on the mechanical properties of both film and substrate.

Comparison of Relaxation Modulus Converted from Frequency- and Time-Dependent Viscoelastic Functions through Numerical Methods

Applied Sciences, 2018
Due to the difficulty of obtaining relaxation modulus directly from experiments, many interconversion methods from other viscoelastic functions to relaxation modulus were developed in previous years.

Viscoelastic Modulus Reconstruction Using Time Harmonic Vibrations

Mathematical Modelling and Analysis, 2015
This paper presents a new iterative reconstruction method to provide high-resolution images of shear modulus and viscosity via the internal measurement of displacement fields in tissues. To solve the inverse problem, we compute the Frechet derivatives of
