This tangential force also induces a torque. In addition, bending and twisting torques are also applied to particles which are proportional to angular bending and twisting -displacements with stiffnesses of :math`k_b` and :math:`k_t', +displacements with stiffnesses of :math:`k_b` and :math:`k_t`, respectively. Details on the calculations of shear displacements and angular displacements can be found in :ref:`(Wang) ` and :ref:`(Wang and Mora) `.
