Description
Summary:The energy method based on the first law of thermodynamics is employed to predict the whole range of stress-strain behavior of twisted hybrid fibrous structures. The model blend yams considered are sheath/core and mixed two-component yarns. Analytical expressions for the load-elongation response including failure are derived as functions of yam geometry and the mechanical properties of component fibers. The mathematical expressions are applicable to the hybrid yam structures made of nonlinear materials with any fractional combination of two components.
