Infrared Thermography For Structural Stress Mapping
Enhance safety and performance with non-contact, full-field thermal imaging solutions for stress visualization in materials.
Overview
Infrared thermography has emerged as a vital tool for stress mapping in civil, aerospace, automotive, and industrial applications. This non-contact, full-field technique uses thermal emissions to detect internal stress variations, heat signatures, and anomalies in materials and structures. By visualizing stress-induced temperature changes, engineers and inspectors can identify weak points, fatigue zones, or defects that would otherwise go unnoticed through traditional methods. As a B2B company serving clients across North America, Pressure Stress Measure provides industry-leading infrared thermography technologies backed by deep expertise in system integration and diagnostics. Headquartered in Vancouver, BC, we offer scalable and precise thermographic systems that support real-time analysis, high-resolution imaging, and automated data logging—helping you streamline inspections, improve safety margins, and reduce maintenance costs.

Case Studies
United States – Bridge Stress Monitoring, Colorado Department of Transportation
Infrared thermography was used to monitor thermal stress signatures across suspension cables of a major highway bridge. The thermal imaging revealed uneven tension zones, prompting corrective tensioning and avoiding a costly structural retrofit.
United States – Aerospace Manufacturing Facility, North Carolina
A commercial aircraft parts manufacturer implemented IR thermography to inspect carbon composite fuselage sections. Stress concentrations were detected along bonded joints, leading to a redesign that improved safety margins.
Canada – Power Utility Thermal Monitoring, Ontario
A provincial utility company deployed infrared drone systems to inspect transmission tower supports and transformer stations for thermal stress buildup. The project helped prioritize maintenance schedules and improve energy infrastructure resilience.
