WebMay 22, 2012 · The photoelastic tensor Cijk depends on structural symmetries of the medium and on the applied strain field. Photoelastic effects are caused by the applied strain since the changed lattice spacing influences the refractive index. Thus, the medium becomes anisotropic, therefore having a nonzero birefringence. http://w0.rz-berlin.mpg.de/imprs-cs/download/sy04_8.pdf

WebThis implies that the correct stress-based statistical mechanics conserves both the force-moment tensor and the Maxwell-Cremona force-tiling area. As such, two variables of state arise: the tensorial angoricity ($\hat{\alpha}$) and a new temperature-like quantity associated with the force-tile area which we name {\it keramicity} ($\kappa$). WebHere we demonstrate that optical second harmonic generation constitutes an even more powerful technique, as it allows extraction of the full strain tensor with a spatial resolution below the optical diffraction limit. Our method is based on the strain-induced modification of the nonlinear susceptibility tensor due to a photoelastic effect.
