Vibration fatigue behaviour analysis of the cracked plate under a uniform temperature field
Abstract
For the thermal fatigue problem of the hypersonic aircraft's plate, a loose coupling analysis method is proposed to conduct vibration fatigue behaviour analysis of the cracked plate under a uniform temperature field.The temperature field is converted into additional loads, and the interaction mechanism between thermal coupling and crack propagation is explored.The modal, dynamic response and fatigue life analyses are conducted synchronously.The numerical simulation method is applied to verify this theoretical method.The results indicate that the analytical method proposed has sufficient computational accuracy, and the influence of the temperature field on vibration fatigue behaviour cannot be ignored.
