AI Technical Summary

Technical Problem

Existing methods for testing the thermal stability of ceramic materials are inadequate for effectively simulating temperature shocks and cyclic thermal fatigue under complex thermal environments, resulting in low testing efficiency. They are unable to sensitively expose potential weaknesses and failure precursors in materials and lack the ability to simultaneously sense and deeply fuse multi-physics field signals.

Method used

By employing a stepped temperature load, combined with a temperature sensing array and acoustic emission signals, and through thermal conduction phase decoupling, thermoacoustic elastic coupling, and spatial topology analysis, dynamic thermal stress characteristics and crack penetration evolution trajectories of ceramic materials are generated, thereby achieving damage spatial evolution and intelligent mode matching.

Benefits of technology

It significantly improves detection efficiency, can actively stimulate the internal thermal shock response of materials in a short time, identify early signs of microscopic damage accumulation, and achieve early warning and accurate diagnosis of the thermal failure process of ceramic materials.

Abstract

The application relates to the technical field of material detection, and discloses a ceramic material thermal stability detection method and system. The method comprises the following steps: applying a step temperature load to the ceramic material, synchronously collecting time sequence temperature distribution data, performing thermal conduction phase decoupling on the time sequence temperature distribution data, separating asynchronous thermal responses, generating dynamic thermal stress features, performing thermal-acoustic elastic coupling on the dynamic thermal stress features, quantifying the micro-crack release rate of the thermal stress gradient value after the thermal-acoustic elastic coupling, generating a critical damage judgment parameter, performing spatial topology analysis on the critical damage judgment parameter, establishing a stress field strong connection path, generating a crack penetration evolution track, performing geometric configuration matching on the crack penetration evolution track and a preset material failure space mode library, and outputting a cascaded thermal collapse early warning signal. The application solves the problem of multidimensional perception and early warning of the internal damage evolution process of the ceramic material under a dynamic thermal load.
