The heat-induced variations in material properties for a layered glass-metal composite material were studied for the case of induction heating and the subsequent composite annealing of the sample. A cylindrical sample of the composite (outer metal cylinder covering the glass cylinder) was used in our experimental study. This sample is an imitation of a brittle rock under a high stress. The simulation complexity originates from superposition of the glass point transition within the glass layer, induction heating for the whole sample, and heat radiation from the external metallic surface. Structural and mechanical relaxation processes in glass are calculated using the Boltzmann-Volterra superposition and the Tula-Narayanaswami-Mazurin-Moynihan (TNMM) model based on introducing a structural temperature as an additional parameter. The paper offers a mathematical model and a simulation method for calculating the temperature field and material properties distributions during the composite production process. The simulation results are presented for various regimes of heating and for glass-metal composite properties. This approach is useful for evaluating the operation modes of the glass layer annealing and for estimating the evolution of laminated composite materials.

层压玻璃金属材料感应加热引起的传热建模

对于感应加热和随后样品的复合退火情况,研究了层状玻璃-金属复合材料的热诱导材料性能变化。在我们的实验研究中使用了复合材料的圆柱形样品(覆盖玻璃圆柱体的外部金属圆柱体)。该样品是在高应力下对脆性岩石的模仿。模拟的复杂性源于玻璃层内玻璃点转变的叠加,整个样品的感应加热以及来自外部金属表面的热辐射。基于引入结构温度作为附加参数,使用Boltzmann-Volterra叠加和Tula-Narayanaswami-Mazurin-Moynihan(TNMM)模型计算玻璃中的结构和机械弛豫过程。本文提供了用于计算复合材料生产过程中温度场和材料特性分布的数学模型和仿真方法。给出了各种加热方式以及玻璃-金属复合材料性能的仿真结果。该方法对于评估玻璃层退火的操作模式以及估计层压复合材料的演变是有用的。
