Webb1 sep. 2024 · The wave theory is integrated into the Euler-Bernoulli beam theory to establish the relationship between the power reflection coefficient and the interface stiffness. The proposed method is verified by establishing a finite element model. The results show that the interface stiffness is accurately identified. WebbThe first step when using the direct stiffness method is to identify the individual elements which make up the structure. Once the elements are identified, the structure is disconnected at the nodes, the points which connect the different elements together. Each element is then analyzed individually to develop member stiffness equations.
