Abstract
The geometric irregularities present inside a structure results in an improper stress distribution caused during manufacturing, which not only affects the strength of the component but also its vibrational behaviour when operated in a fluctuating environment. The emphasis of this paper is to evaluate the stress behavioral characteristics of plates with different cutout shapes. Two different loading conditions with three different types of plates made of Mild Steel are used for this analysis. From the present investigation, it may be concluded that where the max stress occurs. The methodology adopted in this research work is based on the numerical technique of finite element method, which uses SOLID 185 in ANSYS 19.1 solver. For further analysis, the obtained results are validated with previous literature works which were found satisfactory when related to the present study. It may be noted that FEM provides good insight for the determination of stress and deflection, with different parameters.
Highlights
Plates are the structural members which are generally manufactured for fabrication purpose
The stress analysis of a rectangular and square plate with a case of clamped free and supported boundary conditions has been studied in the present study for which the deflections and corresponding stresses are obtained
3) Table 5 signifies that with the change of boundary condition from clamped free to supported type applied to rectangular plate the deformation and maximum stress are more for the square type of cutout whereas components stress and principal stresses are more for triangular type cutout
Summary
Plates are the structural members which are generally manufactured for fabrication purpose. The presence of cut out in plates is especially carried out for inserting bolt and nuts. In order to reduce the weight of the structural members, these cutouts play a crucial role. The stress concentration caused due to cutouts with improper alignment in fastening may lead to high stresses, even sometimes it may cause the failure of the structural members. In order to assess the failure of these components stated in terms of deflection and stresses finite element analysis, a numerical method used as an important tool for finding out the stress behaviour characteristics
