Abstract
The cruciform plane specimens of titanium alloy VT1-0 with a thick of 1 mm were tested to study temperature evolution under fatigue crack propagation. The original contact sensor of heat flow and method of infrared thermography were used to analyze the dissipated energy from crack tip during fatigue tests. A series of experiments was carried out to study the propagation of a fatigue crack under biaxial loading with different biaxial coefficient. It has been shown that heat dissipation caused by fatigue crack propagation under Paris regime can be divided into two stages both under uniaxial and biaxial loading conditions.
