Abstract

The set of operations on diagnosing the changes in the properties of materials due to aging includes accelerated climate tests (ACTs) and pre- and post-ACT performance tests. Along with the use of various methods for diagnosing defects that arise and develop during aging, it is also important to determine changes in the thermophysical, hydrophysical, and other properties of materials subject to long-term operation that are associated with changes in the material structure. In this paper, we present a method for synchronous calculation of changes in thermophysical and hydrophysical properties of materials due to material aging and respective changes to the hygrothermal modes of products under long-term storage and operation. An experimental setup and a method for experimental-analytical determination of the thermophysical properties of materials at variable heating rates, as well as a method of synchronous calculation, are presented. The experimental-analytical determination method was developed using the results of thermal testing of specimens both subjected to ACT and without ACT. The analysis of the test results makes use of the approximation-superposition method to solve the inverse heat conduction problem.

产品长期运行时材料属性和湿热条件的变化以及热物理性质对加热速率依赖性的诊断方法
诊断材料老化引起的性能变化的一系列操作包括加速气候试验(ACT)以及加速气候试验前后的性能测试。在使用各种方法诊断老化过程中产生和发展的缺陷的同时,确定长期运行材料的热物理性质、水物理性质和其他性质的变化也很重要,这些变化与材料结构的变化有关。本文提出了一种方法,用于同步计算材料老化引起的材料热物理性质和水物理性质的变化,以及产品在长期储存和运行条件下的湿热模式的相应变化。本文介绍了在不同加热速率下测定材料热物理性质的实验装置和实验-分析方法,以及同步计算方法。实验-分析测定方法是利用对试样进行 ACT 和不进行 ACT 的热测试结果开发出来的。对测试结果的分析使用了近似叠加法来解决反热传导问题。

期刊介绍: Russian Journal of Nondestructive Testing, a translation of Defectoskopiya, is a publication of the Russian Academy of Sciences. This publication offers current Russian research on the theory and technology of nondestructive testing of materials and components. It describes laboratory and industrial investigations of devices and instrumentation and provides reviews of new equipment developed for series manufacture. Articles cover all physical methods of nondestructive testing, including magnetic and electrical; ultrasonic; X-ray and Y-ray; capillary; liquid (color luminescence), and radio (for materials of low conductivity).
