Abstract A novel and irreversible phase field model accounting for tension-torsion coupling effect and size-effect is constructed in the context of continuum thermodynamics. First, a general framework considering the energy dissipation process influenced by micro and macro force is formulated according to thermodynamically consistent derivation. Next, the framework is specialized by introducing a material parameter called chiral coefficient to characterize the tension-torsion coupling effect within macro force constitutive according to isotropic micropolar elasticity theory. To gain insight of the chiral effect on the fracture behaviors, the analytical solution of uniaxial traction chiral rod is provided based More >
