文摘
- •
Large deflection analysis is performed on cantilever beams with uniform cross section and constant curvature.
- •
Analytical expressions for the position of the center of rotation of the beam free-end section are obtained.
- •
Analytical expressions show that the center of rotation lies in the axis of symmetry of the beam in neutral configuration.
- •
Finite element simulations are performed to compare numerical and analytical solutions.
- •
A final example focuses on the determination of the pseudo-rigid body model.
