Comparison of Analytical and Experimental Approaches for Modified von Mises Truss Behaviour

This work examines a simple planar symmetric truss design (modified von Mises truss) which involves two members subjected to deformation by an applied force, with supporting springs at the ends.The analytical numerical model of the truss structure is formulated using first-and second-order theories of deformation, and the ensuing nonlinear model is solved by applying established techniques.The study subsequently correlates the solution using the results derived from the experimental setup.The two approaches are compared, buckling, snap-through effect and error estimation are evaluated.
