Abstract

In this study, we developed a three-dimensional (3D) human body model and a body sculpting clothing (BSC) which was fitted onto that body to simulate the biomechanical stress variations of the BSC with different porosity structures using the finite element method. The mechanical properties of the BSC with different porosity structures were also examined through the tensile testing. Analytical results indicated that the Von Mises stress of the BSC with a porosity structure of 10.28% varied from 0.076 MPa to 337.79 MPa. As compared with a porosity structure of 35.18%, the von Mises stress varied from 0.067 MPa to 207.30 MPa. The von Mises stress decreased as the porosity increasing. Based on the statistical analysis findings, we obtained a formula to predict the biomechanical relationships (von Mises stress and strain) between the human body and porosity of the BSC. Therefore, these findings could offer potential information in the modification of BSC for pain-relieving applications.

Summary

Introduction

The textiles and fibers in biomedical development have grown rapidly for therapy applications in recent years [1,2]. As previous studies reported that the body sculpting clothing (BSC) has some applications in clinical reports, for example, varicose veins mitigation [6,7,8], scar management [9], etc. Polyamide (nylon) is the most common in functional clothing applications because of its superior chemical and physical properties [13]. Some ways to detect the dynamic pressure of the fabrics have emerged [14,15,16,17], but less proving that the nylon could hold the stresses, or the nylon would not force extra stresses on the human body during the BSC functioning [18,19]. It is necessary to build a biomechanical model to prove the materials’
