Static Analysis of Orthotropic Euler-Bernoulli and Timoshenko Beams With Respect to Various Parameters

In this study, deflections of orthotropic beams along the beam length are calculated by using static analysis according to Euler-Bernoulli and Timoshenko beam theories. Since the mechanical properties of the materials change as the orientation angle of fibers changes, the formulation is carried out using the equivalent Young’s modulus and the equivalent shear modulus. Orthotropic beams are modeled as isotropic beams by using equivalent moduli. Governing equations are derived. Two numerical examples with different orthotropic materials are given for different boundary and loading conditions. The effect of changing the orientation angle of the fibers on the deflection values is also considered. Orientation angle, material properties, length to depth ratio has been considered as parameters in the static analysis of orthotropic beams. Results are also compared with steel which is an isotropic material and presented in the form of tables and graphs which may be useful
