Numerical Simulation of Dynamic Pressure and Displacement for the Top Part of Men's Socks Using the Finite Element Method

Numerical simulation of elastic human body deformation and dynamic pressure and displacement distribution are critical for pressure comfort and optimal design of apparel products. This paper demonstrates an analytical method for simulating dynamic pressure and displacement at the top part of men's socks using the finite element method (FEM). The dynamic pressure is divided into two parts: the first is pressure with time, and the second is pressure with walking. Pressure with time is set at six periods (maximum 12 h). After measuring pressure values in different periods of time and simulating pressure and displacement distribution using ANSYS software, the tendency of pressure and displacement changes with time at the top part of men's socks can be obtained. We divided the walking process into four phases to analyse the variation rule of pressure and displacement changes with movement in this research work. Meanwhile the lower leg cross section is divided into four equal regions according to the angle, and dynamic changes in the area shrinkage mass of each region can be calculated, respectively. All these solutions provide a theoretical reference for the optimal design of the top part of men's socks.
