DEFORMATION STATES OF COMPLEX TWISTED SILK YARN
Main Article Content
Abstract
This article presents the results of theoretical and experimental studies of the stress-strain state of complex twisted silk threads under axial tension. Using a matrix transformation and statistical averaging method, expressions for thread stiffness are obtained, allowing the relative modulus of elasticity to be estimated through longitudinal and transverse deformations. The relative modulus of elasticity of twisted complex thread made from raw silk is estimated as a function of twist.
