Description

technical field [0001] The invention relates to the field of material equivalent performance analysis, in particular to the field of porous material equivalent performance analysis. Background technique [0002] With the rapid development of aerospace technology and other engineering technologies, the demand for lightweight and high-strength materials is more urgent. Therefore, the research on porous materials including three-dimensional lattice materials has been paid more and more attention by scientific researchers. [0003] The modern aerospace industry often requires its components to provide power, perform sensing, heat insulation and other multi-functional applications while carrying loads, thereby greatly reducing its weight. Therefore, in aerospace-related design, it is necessary to consider the functional application requirements of the structure, and at the same time, its mechanical properties such as stiffness and strength must meet certain conditions. [0004] ...
