A uniform Steel strut (material Modulus of Elasticity 200 GN/m2, Poisson’s Ratio 0.3) oflength 0.5m and width 100 mm is restrained as appropriate at one end and under an axialtensile load of 25 KN applied to the other end face. It has been initially designed with a thickness of 5mm. This gives a hand calculated stressvalue of 50 MN/ m2, which is a quarter of the material’s Yield Stress, of 200 MN/m2, givinga factor of safety of four. Conduct computer FEA simulations applying element types(tetrahedral, hexahedral) and a range of element sizes (2mm, 5mm & 10mm), presenting findings in a tabulated format.
