In this study, we first determine the self-equilibrium configuration of the strand that has no excessive twists, say torque-balanced strand. It keeps the self-equilibrium configuration without any external loads, due to torque balance of contact force between filaments by geometrical and physical twist. We determine the self-equilibrium solution of the strands based on generalized Kirchhoff rod model. Filament is assumed to be a linear elastic material, and we consider both the geometrical twist such as helically wound side filaments around a core filament, and physical twist. In the formulation, we take into account the radial contact in three-dimensional space. Next, we study constitutive behavior of torque-balanced strand under tensile load. Then, we examine the effects of microscopic geometrical and material factors such as the physical twist and Young's modulus of the filament on the macroscopic constitutive behaviors of 1+n strands under tensile loading.
