“…It is observed that SCF and SIF depend on the material parameters for anisotropic material, while it is independent of material properties in case of isotropic materials. N. Troyani [12], showed that theoretical SCF also depends on the length of the member in addition to the established other geometric parameters. He compared the value of SCF for short plate and long plate for same loading and boundary conditions and introduced transition length for short members.…”

Abstract.A number of analytical, numerical and experimental techniques are available for reduction of stress concentration factor around discontinuities. Determination of stress concentration factor around different discontinuities in a rectangular plate made up of different materials under different loading conditions has been reported in literature. Mitigation of stress concentration factor although, an area with very earlier findings however, is lesser reported in the literature. An attempt has been made in the present work to present an overview of various techniques developed for analysis and mitigation of stress concentration factor. The methods compared are tabulated with their findings. No single method can be suggested for each and every condition to the reduction of stress concentration; still the present comparative study will help in deciding the stress mitigation method for a particular case. Singularities of circular hole in rectangular plate and elliptical hole in rectangular plate are considered in present study. Separate nomenclature has not been given and the terms are defined as and where used. References are used as per their occurrence and not in a particular order.

“…Ting et al [11,12] presented the alternative method to study the stress distributions of the multiple Ukadgaonker and Rao [13] proposed a general solution for stresses around hole in symmetric laminates under inplane loading by introducing a general form of mapping function and an arbitrary biaxial loading condition to the boundary conditions, and the basic formulation is extended for multilayered plates. Troyani et al [14] have determined the in-plane theoretical stress concentration factors for short rectangular plates with central circular holes subjected to uniform tension using finite element method.…”

The problem of finding the stress concentration factor of a loaded rectangular plate has offered considerably analytical difficulty. The present work focused on understanding of behavior of isotropic and orthotropic plate subjected to static in-plane loading using finite element method. The complete plate model configuration has been analyzed using finite element method based software ANSYS. In the present work two parameters: thickness to width of plate (T/A) and diameter of hole to width of plate (D/A) have been varied for analysis of stress concentration factor (SCF) and its mitigation. Plates of five different materials have been considered for complete analysis to find out the sensitivity of stress concentration factor. The D/A ratio varied from 0.1 to 0.7 for analysis of SCF and varied from 0.1 to 0.5 for analyzing the mitigation of SCF. 0.01, 0.05 and 0.1 are considered as T/A ratio for all the cases. The results are presented in graphical form and discussed. The mitigation in SCF reported is very encouraging. The SCF is more sensitive to D/A ratio as compared to T/A.

“…When it comes to research the phenomenon of stress concentration around a circular hole in the majority of cases, a thin plate weakened by a circular hole loaded with a certain load is analyzed [8][9][10][11][12][13]. The problem narrows down to the exact determination of stress distribution around the hole, as well as determination the stress concentration factor.…”
