Safety Evaluation for Pure Titanium by Lock-in Infrared Thermography [PDF]
The lock-in infrared thermography has been applied to an estimation of fatigue limits at several stress ratios, i.e., R=-1, 0.05, and 0.5, for commercially pure titanium (CP-Ti JIS grade 2) at room temperature.

A local defect resonance for linear and nonlinear ultrasonic thermography [PDF]
An efficient wave-defect interaction is the key to a high thermal response of flaws in ultrasonic thermography. To selectively enhance defect vibrations a concept of local defect resonance is developed and applied to ultrasonic activation of defects ...

New Developments in IR Lock-In Thermography [PDF]
Abstract Lock-in thermography based on an infrared camera has proven to be a useful tool for failure analysis of integrated circuits (ICs). This article discusses four novel technical developments of lock-in thermography. These developments are blackening the IC surface with colloidal bismuth, the synchronous undersampling technique ...
