PartialCompliant

Base model for a 1D translational compliant connection.

This partial component establishes the fundamental kinematic and force relationships for a generic compliant connection between two 1D translational mechanical flanges, flange_a and flange_b. It defines the relative displacement, $s_{rel}$, between the flanges and the internal force, $f$, transmitted through the compliant element. The defining equations are: Relative displacement: $s_{rel}=flang{e}_b.s-flang{e}_a.s$ Force on flange_b: $flang{e}_b.f=f$ Force on flange_a: $flang{e}_a.f=-f$ This model is partial and intended to be extended by concrete components that will specify the constitutive law for $f$ based on $s_{rel}$ and/or its time derivatives (e.g., a spring or damper).
