Stress analyses and geometry effects during cyclic loading using thermography

Article Abstract:

A high-speed and high-sensitivity thermographic-infrared (IR) imaging system is used to investigate the temperature evolutions of SA5331B1 steel specimens during high-cycle fatigue experiments. The thermography technology provides an effective means to 'watch' and 'quantify' the heat-evolution processes such as the mechanical-damage behaviors, which can open up new opportunities for insitu studying mechanical, and phase-transformation behaviors in detail.

Goodman diagram via vibration-based fatigue testing

Article Abstract:

A new vibration-based fatigue testing methodology for assessing high-cycle turbine engine materials fatigue strength at various stress ratios is presented. The performance of the methodology is demonstrated with experimental results for mild steel, 6061-T6 aluminum, Ti-6Al-4V plate specimens subjected to a fully reversed bending, unaxial stress state.
