Comparison of Elasticity Methods, Finite Elements, Software in Solving the Particular Problem of Strength of Materials

In this study, the deflection of a specific beam under wide and point loads and a specific bending torque is obtain. The size of all forces and lengths are known. This structure is characteriz by two separate parts; the cross-section and moment of inertia of each are different, which is express numerically. The boundary condition for the beam is that it is closed at the initial and end sides by a fixed-support, the two beams are connect by a pin. There are three ways to solve it. First, we use the one-dimensional finite element method to obtain the deflection, rotation angle, shear force and shear torque along the beam. Then, using the theory of elasticity, the problem is solved to obtain all of the above in this way. also using the Abaqus analytical software, the answers are obtain. Finally, the answers to the three modes will be examined and compared.
