Design of a Beam Structure for Failure Prevention at Critical Loading Conditions

Owunna Ikechukwu,Ikpe Aniekan. E and Satope Paul

Abstract: To avoid failure in most engineering designs, von-mises failure criterion must be met. This criterion requires that the stress a body is subjected to is less than the yield strength of the material of the body. In this analysis, a beam structure has been designed with CATIA software to ensure that the von-mises criteria is met. This was done with critical evaluation of the mass requirement and the pivot constraints on the body. The first load case considers a total force of 18kN while the second load case considers a force of 9kN. The final weight of the initial model was 19.989kg. The maximum von-mises stress obtained from the initial analysis for load case 1 was 1560MPa whereas, the maximum von-mises stress obtained from the initial analysis for load case 2 was 530MPa. For the final design analysis, weight of the final model was 14.329kg. The maximum von-mises stress obtained from the final analysis for load case 1 was 102MPa whereas, the maximum von-mises stress obtained from the final analysis for load case 2 was 101MPa. Hence, one of the methods that failure can be avoided in beam design is to ensure that the maximum allowable stress is not exceeded
