Determination of thermal stress state of the viewing windows of food machines, made of triplex

Rudyak U.A.

The article presents data on the characterization of the stress-strain state (SSS) viewing windows food machines, made of laminated glass. Range during the study: from +20C to -60C. The variants of the four types of triplets - homogeneous and heterogeneous, with or without a frame. Investigations were carried out polarization-optical method, and the optical anisotropy was measured by the compensation method Senarmona as for materials with low optical sensitivity, such as inorganic silicate glass, strip method does not provide the necessary accuracy. Based on the experimental results suggest the influence of heterogeneity on the frame and thermal stress state food inspection windows machines, made of laminated glass.
