Research into the Impact of the Beam Material and Embedding on the Size of the Maximum Deflection and Stress by Using Numerical Simulation

Abstract:

The most frequent research methods applied in various areas of scientific research are computer modelling and numerical simulation. The trend of using finite element method (FEM) gradually replaces classical methods of exploring phenomena. The method is suitable for investigating technical phenomena in the field of construction, mechanics and strength, as well as in other disciplines. Its suitability for the area of ​​strength will be demonstrated in the current paper which presents solutions to various embeddings of a beam under bend. The beam was loaded with an external uniformly distributed load q(x) along its entire length. The research aim was to determine the maximum load and maximum deflection of the beam depending on the beam position and the material used. The beam under bend was selected as the most commonly used structural element. Analytical solution to bending moment and displacement forces is suitable for simple beam loads. Modelling and numerical simulations provide solution to complex problems and different load variations, while identifying changes in material properties of the structural element under consideration. The results are then evaluated and judged on the basis of the maximum strength of the structural material, while meeting the safety condition of the maximum load or maximum deflection. Modelling via FEM is a flexible research method applicable in all research areas.
