cb_tenf f

\(T_F\) - contact bond tensile strength in units force with default value 0.0.

cb_tens f

\(T_{\sigma }\) - contact bond tensile strength in units stress. This is read-only property.

cb_shearf f

\(S_F\) - contact bond shear strength in units force with default value 0.0.

cb_shears f

\(S_{\sigma }\) - contact bond shear strength in units stress. This is a read-only property.

cb_state i

\(B\) - contact bond state with default value 0. This is a read-only property.

dp_force v

\(\mathbf{F^d}\) - dashpot force in units force. Expressed in the contact plane coordinate system. This is a read-only property.

dp_mode i

\(M_d\) - dashpot mode with default value 0.

dp_nratio f

\(\beta_n\) - normal critical damping ratio with default value 0.0.

dp_sratio f

\(\beta_s\) - shear critical damping ratio with default value 0.0.

emod f

\(E^*\) - effective modulus in units force/area. This is a read-only property.

fric f

\(\mu\) - friction coefficient with default value 0.0.

kn f

\(k_n\) - normal stiffness in units force/length with default value 0.0.

kratio f

\(\kappa^*\) - normal-to-shear stiffness ratio. This is a read-only property.

ks f

\(k_s\) - shear stiffness in units force/length with default value 0.0.

lin_force v

\(\mathbf{F^l}\) - linear force in units force with default value \(\mathbf{0}\). Expressed in the contact plane coordinate system.

lin_mode i

\(M_l\) - normal-force update mode with default value 0 (absolute update mode). Incremental normal-force update mode is set with \(M_l\) = 1.

lin_slip b

\(s\) - slip state. This is a read only property.

rgap f

\(g_r\) - reference gap in units length with default value 0.0.
