High-Precision Photoelastic Coating Systems For Stress Analysis
Explore full-field, non-contact stress visualization tools tailored for structural testing, material science, and mechanical systems.
Photoelastic Coating Systems
Photoelastic Coating Systems enable high-resolution, full-field stress analysis on the surface of mechanical components, structures, and test samples. These systems use optically sensitive coatings that exhibit birefringence under stress, allowing for visual inspection and quantitative analysis of stress patterns when viewed under polarized light. Digital Image Correlation (DIC) systems are often integrated to provide real-time measurement and interpretation. Suitable for both laboratory and field applications, these systems are invaluable for non-destructive testing, failure diagnostics, and design optimization. With a strong foothold across North America, Pressure Stress Measure delivers reliable, scalable Photoelastic Coating Systems for a wide range of industries. Headquartered in Vancouver, BC, we serve B2B clients with a commitment to innovation, quality assurance, and hands-on technical support.

Case Studies
Aerospace Component Testing (U.S.)
An aircraft manufacturer in Texas used our Photoelastic Coating System to study stress concentrations around fastener holes in wing spars. By analyzing the birefringent patterns under various load conditions, they optimized the hole geometry, reducing fatigue failure by over 40%.
Civil Bridge Monitoring (U.S.)
A research team in Pennsylvania deployed our systems to assess stress behavior in bridge deck reinforcements. Combined with GAO Tek’s strain sensors, the study validated predicted FEA stress contours, enhancing future design reliability.
Pressure Vessel Evaluation (Canada)
A Canadian oil & gas firm embedded photoelastic coatings on a pressure containment shell to monitor real-time stress during hydrostatic testing. The insights led to design updates and compliance with CSA S6 standards.
