Tiivistelmä
Computation in Engineering Analysis are possible using a software COMSOL Multiphysics. Multiphysics COMSOL is a simulation tool that understands, predicts and optimize based on a physics by using a numerical simulation. The software utilizes the finite element method as a numerical technique. The research paper helps to clarify the best method to test and analyze the material properties of an object. The COMSOL simulation is based on Euler Bernoulli beam model and 3D
solid mechanics.
The results are compared based on the theory and experimented results. The material is selected from COMSOL list of materials. The material is predefined and set to be STEEL ASI 4340.The test method is based on three deformations which are: first, uniaxial elongation analyses using a rectangular cross-section geometries by using displacement result: second, the bending deformation due to the force exerted at a midpoint using a rectangular cross-section beam geometries: thirdly, the torsion deformation of the cylindrical beam in which the angle of twist is measured.
The beam model showed a precise accuracy with the analytical computation. In the 3D model, there is error difference in the values when compare to analytical solution. The error value in 3D solid is higher in axial deformation. The time and physical memory are also considered and compared while studying the models. The time and memory cost are better in beam model than 3D solid model.
