Abstract

It is shown that for linear isotropic elastic and viscoelastic materials a single type of 1-D set of tension experiments with optical measurements supplies sufficient stress and strain data to completely characterize all moduli (including Young's, shear and bulk ones) and all compliances. This is accomplished directly in real time space without the use of integral transforms and/or Poisson's ratios and includes the complete history of loading and of displacements including their build ups. Additionally, several approaches to the determination of instantaneous moduli from 1-D quasistatic and dynamic experimental data are presented and evaluated.
