Stress visualization in geometrically complex structures using Thermoelastic Stress Analysis and Augmented Reality

We present a framework for the visualization of mechanical stress using augmented reality (AR) using Thermoelastic Stress Analysis (TSA). The 2D stress images generated by TSA are converted to a 3D stress map using computer vision technology and then superimposed on the real object using AR. Our framework enables in-situ visualization of stress in geometrically complex structural components, which can assist in the design, manufacture, test, and through-life sustainment of failure-critical engineering assets. We also discuss the challenges of such a TSA-AR combination and present a case study that demonstrates the performance and significance of our system.We present a framework for the visualization of mechanical stress using augmented reality (AR) using Thermoelastic Stress Analysis (TSA).
