Elements

The finite element method started with significant promise in the modeling of several mechanical applications. Besides, the principle of minimization of energy forms the primary backbone of the finite element method. The principle of minimization of energy governs his. It states that when a boundary condition (like displacement or force) is applied, the body can take numerous possible configurations. Before moving directly to these conditions, it will be fair to visit the simplified representation of the structure and the actual representation of the load over it. The structural constraints are presented in Fig. 3a, which indicated that axial displacement on the marked areas is restrained for all directions. The applied load is presented in Fig. 3b which the assumed passenger load is 4000 N. a b

Stress analysis is an integral part of engineering science, as a failure of most engineering components is usually due to stress. Stress is defined as the result of forces that lead to internal particles' reactions and affect an object in
