摘要
随着时代的发展,科技水平的快速崛起成为了时代的典型特征,尤其在高新技术制造、微电子科技、医疗、航空航天技术等领域发展尤为迅速。伴随着工作环境的极端性,以及制造加工工艺的缺陷等问题,热传导的非傅里叶效应显著,严重制约着相关技术的发展,因此,研究医疗和工程领域常见的结构和材料的非傅里叶断裂性质至关重要。阐述了非傅里叶效应的原理,经典热传导理论和非傅里叶热传导理论的区别以及非傅里叶热传导理论的适用环境,指出了非傅里叶热传导理论对医学、微电子、航天技术等工程领域的积极作用,以及相关领域的断裂力学研究现状,对工程领域中的热防护材料和结构的设计和应用有着重要的借鉴作用。
With the development of the times,the rapid rise of science and technology has become a typical feature of the times,especially in high-tech manufacturing,microelectronics technology,medical treatment,aerospace technology and other fields of rapid development.With the extreme working environment and the defects of manufacturing process,the non-Fourier effect of heat conduction is significant,which seriously restricts the development of related technologies.Therefore,it is of great importance to study the non-Fourier fracture properties of common structures and materials in medical and engineering fields.This paper expounds the principle of non-Fourier effect,difference between the classical theory of heat conduction and the non-Fourier heat conduction theory,and the applicable environment for the non-Fourier heat conduction theory,then points out the positive effect of non-Fourier heat conduction theory on the engineering fields such as medicine,microelectronics,aerospace technology,and the present status of fracture mechanics research in the related fields.It has important reference value to design and application of the thermal protection materials and structures in the engineering field.
