Finite element simulation of pressure and volume shrinkage of the top part of socks using ABAQUS

Abstract

How to achieve an effective balance between functionality and comfort is a key factor in the design of the top part of socks. In order to make the top part of socks more consistent with the characteristics of pressure distribution at the lower leg while improving pressure comfort, the lower leg and foot of the human body was taken as the research object, and Mimics software was used to establish a three-dimensional model of the lower leg and foot. ABAQUS software was applied to simulate the pressure distribution state of the lower leg at the top part of the socks and the stress trend in each region of the lower leg after wearing experimental socks. In order to further study the compression state of the lower leg section at the top part of the socks after wearing the socks, the section was divided into eight regions according to the angle, and the functional relationship between pressure and displacement was obtained through curve fitting. Meanwhile, the volume shrinkage of the eight regions of the lower leg section after compression was calculated, respectively. Results showed that the curvature radius of the lower leg, the thickness of the soft tissue and the position of the skeleton jointly affected the pressure and displacement values after wearing socks, and the distribution trend of volume shrinkage was different at each region of the lower leg section. The conclusion could provide the theoretical basis for the optimization design of the tightness degree of the top part of socks in different regions, and provide a data reference for the research and development of pressure socks that meet the required pressure comfort.
