DisplayImg 7 TSAvis

Software for thermal stress analysis using lock-in thermography

Visualize stress distributions and dissipation processes without contact. DisplayImg 7 TSAvis is a specialized software module for thermal stress analysis (TSA) under dynamic loading. The software evaluates minute temperature-related signal changes synchronously with the external load, enabling visualization of stress distributions, local stress concentrations and dissipative processes within the material.

In addition to real-time lock-in analysis, TSAvis supports multi-harmonic evaluation, ROI statistics, profiles and isotherms. Typical applications range from crack initiation and propagation analysis to adhesive and joint inspection, composite material evaluation and validation of numerical simulation results.
