“…Thus, using this commercially available equipment named a stress analyser, imaginary calculation was conducted using temperature image changes caused by periodically given ultra-low distortion. The first trial of the dynamic use of thermography to display temperature images was probably conducted to detect fatigue-related heat emission in composite materials (Reifsnider and Williams, 1974). ; however, first-stage thermography could not produce successive images to show the deformation process.…”

“…Reifsnider and Williams in 1974 [28] used thermography to monitor stress induced damage in composites while in 1975 [29] Charles et al employed TSA in artificially notched samples. In 1988, Stanley and Chan in [30] performed the TSA method to assess damage in composite materials.…”

“…Reifsnider and Williams [1] showed an attempt to measure and characterize the surface temperature rise of flawed plate specimens, made of composite material during the cyclic straining process. Charles et al [2] used a scanning infrared camera to predict the location of impending fatigue damage, to monitor growing fatigue cracks and to map the temperature fields around stress concentrations.…”

Lock-in thermographic methodology for fatigue assessment and nonlinear stress measurement

This scientific paper presents two approaches, based on the thermographic technique, for fatigue assessment and stress measurement. The first method, based on the lock-in thermography, is an energy approach; it takes intrinsic dissipation as the fatigue indicator, and evaluates the fatigue limit through a drastic change in the rate of dissipated energy. The second method is the Thermographic Method, which takes temperature increment as the fatigue indicator to assess the fatigue limit of materials and mechanical components. The Energy Approach of the Thermographic Method is based on the energy expression of linear fatigue cumulative damage hypothesis and allows the rapid assessment of the whole S-N curve. This research paper advances this quantitative thermographic method for residual fatigue life assessment. A stress analysis technique, known as SPATE (Stress Pattern Analysis by Thermal Emissions), measures the temperature variation due to the thermoelastic effect for stress determination, which could be unfaithful when the stress level is relatively high. Thus we proposed to use the Thermographic Method to assess the cyclic stress amplitude σ a through the S-N curve. Good predictions were achieved using all the methods.
