Abstract

The invention discloses a thermal performance analysis method for a material with straight cracks or heterogeneous splicing. The method comprises: analyzing and reasonably assuming a model by analyzing the actual physical process of the crack and heterogeneous splicing problems of a material; providing a mathematical description and control equation for describing the cracks and the heterogeneoussplicing heat transfer process of the material; proposing an interface boundary condition for describing a physical quantity discontinuity condition on an interlayer according to the characteristics of the parameters and the thicknesses of the cracks and the heterogeneous splicing lines, the heat conduction coefficients and the like; and discretizing the heat conduction model of the fracture material or heterogeneous splicing material by adopting a mathematical method to obtain a discrete linear equation set; solving the discrete linear equation set, and analyzing the result. The method can reduce the research and development cost and shorten the research and development period, is quick and accurate, and can conveniently and rapidly predict the temperature change of the crack material orthe heterogeneous splicing material in the heat conduction process through a mathematical model and a numerical simulation method, so that the heat transfer performance can be evaluated and guided.

Description

technical field [0001] The invention relates to the application field of cracked or heterogeneously spliced ​​composite materials, and provides a short-period, low-cost, and effective numerical simulation method for analyzing the heat conduction process of heterogeneously spliced ​​materials with straight interface types or cracked materials. Background technique [0002] Due to their superior strength, stiffness and designability, composite materials are widely used in different engineering fields such as aerospace, shipbuilding, construction, machinery manufacturing, etc., especially in aerospace vehicles, and are gradually used in important parts. , developed into the main bearing engineering structural material. However, composite materials and heterogeneous splicing materials are likely to cause interlayer delamination or cracking during service, resulting in a decrease in structural strength and stiffness, which greatly affects the use of composite materials. For exam...
