This paper investigates the deflection and bending stress in a cantilever beam of uniform rectangular cross section with a point load using a 3D Finite Element (FE) model. The results are validated using the Bernoulli-Euler’s elastic curve theory equations. The research aims to study and analyse the static analysis of a rectangular beam considered to be isotropic. During this analysis, the displacement is assumed to be small, the material exhibits a linear stress strain relationship i.e.: obeys Hooke’s law, there is no change of magnitude, orientation or distribution of the load applied and the effect of gravity are negligible hence with of the beam is not accounted for in this analysis. The simulation is carried out in the Autodesk Inventor stress analysis environment and validated using theoretical methods after which the effects of point loads on structural integrity and mechanical properties are studied.
