Fe Snake Script [hot] Jun 2026

A planar snake is modeled as a serial chain of ( n ) beam elements of equal length ( L ). Each node ( i ) has three degrees of freedom (DOFs): ( (u_x, u_y, \theta_z) ). External forces include:

For element ( e ): [ U_e = \frac12 \int_0^L \left( EA \varepsilon^2 + EI \kappa^2 + GA_s \gamma^2 \right) dx ] where ( \varepsilon ) = axial strain, ( \kappa ) = curvature, ( \gamma ) = shear strain, ( A ) = cross-sectional area, ( I ) = moment of inertia, ( E ) = Young’s modulus, ( G ) = shear modulus, ( A_s ) = shear correction factor.
