+
+SteelDRCV Material
+^^^^^^^^^^^^^^^^^^
+
+This command constructs a rate-dependent steel material with phenomenological bond-slip pinching for cyclic loading. It extends the SteelDRC model by incorporating two mechanisms: (1) strain-rate effects via an additive Voigt-type viscous overstress, and (2) quadrant-dependent pinching for stiffness degradation at the steel--concrete interface.

+
+.. note::
+
+   **Strain-rate effects.** The viscous overstress is computed as :math:`f_{sd} = \mathrm{sign}(\dot{\varepsilon})\; k_{\mathrm{rate}}\; |\dot{\varepsilon}|^{n_{\mathrm{rate}}}` and added to the rate-independent mechanical stress :math:`f_{sh}` so that the total stress is :math:`f_s = f_{sh} + f_{sd}`. The model requires the analysis time step ``ops_Dt`` to be defined before the material is invoked.
+
+   **Pinching.** The pinching formulation is governed by two dimensionless parameters: the curvature factor :math:`\lambda` and the sharpness exponent :math:`n_p`. These control the stiffness reduction observed when reinforcing bars cross cracked concrete sections due to bond-slip at the steel--concrete interface.
+
+   All input values must be in consistent units. The model uses engineering stress and strain.
