Finite element simulation of pressure, displacement, and area shrinkage mass of lower leg with time for the top part of men’s socks

Abstract

This paper reports a study of pressure, displacement, and area shrinkage mass distribution with time between the human body and compression garment using finite element method according to ergonomics. After creating the function between pressure/displacement ratios and angle, it indicated that multiple relationship between pressure and displacement almost unaffected by wearing time. The corresponding displacement value can be calculated on the premise of the known pressure value at any point and any time during the wearing process by functional equation. Considering displacement distribution, we divided the lower leg into 12 equal regions according to angle, and then calculated area shrinkage mass of each region. According to area shrinkage mass distribution, the top part of men’s sock could be designed with different degree of tightness combined with subjective pressure comfort. All these solutions supplied a theoretical reference for optimal design of the top part of men’s sock.
