The thermal effect is one of the main effects of directed energy interaction with materials. Currently, research on thermal effects between directed energy and materials have been extensively developed. However the system level thermal effect and thermal failure evaluation is relatively less, especially the system level thermal failure evaluation lacks of effective analysis method. In this paper, the method of reliability analysis based on fuzzy inference and Monte-Carlo method is proposed to quantitatively evaluate the thermal failure process of the system. Based on the above method, simulation verification is performed. The component model is established and the boundary conditions of the directed energy are applied. Through the simulation, the thermal failure quantitative evaluation results of the system are obtained. The thermal failure rules of the system are studied and the results can be used for system level radiation effect research.
The calibration of acoustic emission sensor is important for acoustic emission quantitative evaluation. To carry out the sensor calibration, one way is to find a reference acoustic emission source, such as a falling solid ball, a fracturing pencil lead, with energy evaluation to obtain the characteristics of the reference source. One way is to use a reference sensor to measure the pressure or the normal velocity at the surface, including the capacitive transducer and the laser interferometer. The other is using reciprocity method. Frequency characteristics of amplitude of absolute sensitivity of both the Rayleigh and longitudinal waves could be determined by purely electrical measurement without the use of mechanical sound sources of reference transducers. In this paper, the progress of the methods of the AE sensor calibration was given. The principles and the merits and faults of each method are discussed. In this paper the rapid calibration method by pulse exciting transducer was also discussed in different wave mode, as well as Face to Face method.
