Characterization of Mechanical and Optical Properties of Rheo-optically Simple Materials

open access: yesBulletin of JSME, 1979
Classical photoelasticity can be extended to analyse the stress-strain fields in viscoelastic materials. In this photoviscoelastic analysis, it is necessary to record and approximate with mathematical formulae a complete time history of the mechanical and optical characteristic properties of the viscoelastic materials.
