AbstractWe present a novel physically‐based method to visualize stress tensor fields. By incorporating photoelasticity into traditional raycasting and extending it with reflection and refraction, taking into account polarization, we obtain the virtual counterpart to traditional experimental polariscopes.

RGB Photoelasticity: Review and Improvements
Strain, 2010 This paper considers the main developments of RGB photoelasticity with reference to the maximum measurable retardation. In this paper, a new procedure based on the standard error function evaluated on a subset of the calibration array is also proposed ...

Photoelasticity with finite deformations
Zeitschrift für angewandte Mathematik und Physik ZAMP, 1970In this paper we consider the propagation of plane electromagnetic waves in a non-absorbing material which is subjected to finite deformations. It is assumed that the material is isotropic when undeformed and when no electromagnetic fields are present and that it is centrosymmetric.

Isochromatic fringes in photoelasticity
Journal of the Optical Society of America A, 2000The structure of the isochromatic fringe pattern in a two-dimensional photoelastic model is investigated with the phase diagram method of the theory of dynamic systems. Isochromatics are interpreted as phase paths (or level curves) of a Hamiltonian system. Possible singularities of the fringe pattern are analyzed.

Photoelastic tensor of tellurium
Applied Optics, 1989We report the determination of the magnitude and sign of the unknown photoelastic coefficients of tellurium, p(65), p(56),and p(44), as well as all of the unknown signs of the previously determined photoelastic coefficients.

Polycarbonate as a photoelastic material
Strain, 1980The use of commercial grade polycarbonate for photoelastic models is evaluated and hints given on methods of annealing, machining, stress freezing and preparation of slices for viewing.

Digital holographic photoelasticity
Applied Optics, 2017A new technique using digital holography to study the photoelastic isochromatic and isopachic fringes and their respective phases is reported. Our detailed theoretical and experimental analysis shows the possibility of whole-field analysis of every section of stressed photoelastic materials.

Photoelasticity in quasicrystals
Pramana, 1994The maximum number of non-vanishing and independent second order photoelastic coefficients required by the seven pentagonal and the two icosahedral point groups 5(C5),\(\bar 5\)(S10),\(\overline {10} \)(C5h),\(\overline {10} \) m2(D5h), 52(D5), 5m(C5v),\(\bar 5\) 2m(D5d); 235(I), 2/m\(\bar 3\)\(\bar 5\)(Ih)—that describe the quasicrystals symmetry ...

Three-Dimensional Photoelasticity
Journal of Applied Physics, 1951The classical Sommerfeld-Runge method for deriving the laws of geometric optics in isotropic inhomogeneous media from Maxwell's equations is applied to problems in ``weakly'' anisotropic and inhomogeneous media. This leads to a generalized Hamilton-Jacobi partial differential equation for the phases of the two waves (eikonals) which can propagate with ...

In transmission photoelasticity, stresses and strains are not directly measured on the real piece, but on a photoelastic model. To improve accuracy, the photoelastic material type, size of the model, its thickness, and the applied load must be chosen properly. In this paper, the influence of selectable parameters in a photoelastic transmission analysis
