Abstract

The invention discloses a design method of an axis tension member based on a microscale and the axis tension member. The design method comprises the following steps: determining the size of macroscopic particles according to the actual type of a material and an external environment; then determining a Morse potential function parameter; then establishing a microstructure model, establishing a mesostructure model and establishing a macrostructure model; and finally, acquiring the minimum value of the thickness of the axis tension member. According to the method, an existing material strength calculation method is supplemented, and reasons of material deformation and damage are analyzed essentially. The design based on the design method is more accurate, and the cost can be greatly saved.

Description

technical field [0001] The invention belongs to the technical field of molecular dynamics analysis, and relates to a design method of an axial tension member and an axial tension member, in particular to a method for analyzing the tensile strength on the basis of studying the internal fine structure composition of materials and the effect of force. Design method of steel plate and axial tension member. Background technique [0002] The existing steel structure design principles are all obtained through experiments, and are mostly based on experience when adopting them. Without considering the microscopic composition and performance of the material essence, there is no mature microscopic essence explanation for the stability problems, fatigue problems, low temperature brittleness, and welding residual stress that are often encountered in steel structure theory. This does not consider the working environment factors. The influence of structural design is insufficient, and the...
