Numerical And Experimental Investigations of Nonlinearity Behaviour In A Slender Cantilever Beam

open access: yesMATEC Web of Conferences, 2018
Nonlinear problem is always occur in slender structures that are usually characterized by large displacements and rotations but small strains. Linear design assumption could lead to premature failure if the structure behaves nonlinearly.
