Stress Analysis of Finite Steel Plate with a Rectangular Hole Subjected to Uniaxial Stress Using Finite Element Method

Sohanur Rahman

The orientation of a rectangular opening in a plate subject to a uniaxial stress has an important effect on stress distribution. In this paper, the effect of von mises stress has been investigated for various corner radius of rectangular opening to opening width ratio of a finite rectangular plate, from this analysis the suitable model has been selected and on the basis of that model the effect of von mises stress also has been investigated for various opening width to length ratio and from this analysis most desirable model has been selected when the value of opening width to length ratio is 0.5. Openings are reinforced to restore partially the effective cross section area and reduce stress concentration. In this paper, the effect of von mises stress on various types of reinforcements have been investigated and from this analysis it has been observed that single doubler plate gives the most suitable reinforced model. Finally, the convergence test has been performed for the most suitable reinforced model. The aim of this paper is to analyze a finite steel plate with a rectangular hole subjected to uniaxial stress and observe the effect of variation in reinforcement.
