外文摘要：The calculation model for analysis of acoustic emission response in plate structure caused by a finite crack under moving point heating source is proposed. The solutions of the problem are divided into the following ones: (1) dynamic displacement field under zero state initial mechanical boundary and moving point heating source with heat conditions, which is solved by the moving coordinate method; (2) the problem on dynamic displacement caused by the instantaneous application of the constant stress on the crack surface, which is solved by numerical solution method to the standard Fredholm integral equation that is reduced by the Laplace transform to the mixed mechanical boundary. Using the obtained solutions, the dynamic acoustic emission response in the plate structure caused by a crack and moving point heating source is discussed in detail.
