“…In studies conducted by Joshi et al, stress concentration in isotropic and orthotropic plates under uniaxial and biaxial loading was investigated [31,32]. In both papers, they studied the effects of two key parameters rotation angle of cutouts and bluntness parameters on the amount of stress concentration.…”

The purpose of this paper is to present a new method based on the regression analysis for estimating stress concentration factor of different cutouts in orthotropic plates. The existence of an explicit relation in terms of mechanical properties can be an approach for analyzing the stress of viscoelastic plates. Little research has been conducted to provide explicit relationships to calculate the theoretical stress concentration. In the present study first, using different values of the mechanical properties of the composites, stress concentration factor was calculated by employing an analytical solution based on the complex variable method. Then, using multiple linear regression, an explicit mathematical relation for different cutouts was presented with the purpose of estimating stress concentration factor in terms of mechanical properties. The results showed that the regression model is able to predict circumferential stress with a maximum error of 1% for circular, elliptical, triangular and square cutouts. Also, the evaluation of the model with k-fold cross validation method and also comparison with other studies showed that it is possible to rely on the present estimation. Working with the regression models, which are presented in this article, is very simple and can be practical.

“…Several studies on the SCF in circular holes in thin and thick plates Newman, 1992, 1995) subjected to uniaxial and biaxial loading (Wu and Mu, 2003) in isotropic Optimization of the strain concentration factor 537 and orthotropic plate systems (Kotousov et al, 2010;Kotousov and Wang, 2002;Li et al, 2000;Berto et al, 2004;She and Guo, 2007) were conducted. The transverse analysis, in terms of displacements and stresses, of isotropic and orthotropic plates with central squared (Kalita et al, 2015) and triangular (Jadvani et al, 2017a) cutouts under uniaxial (Kalita et al, 2015;Jadvani et al, 2017a) and biaxial loads (Joshi et al, 2017) was also discussed. Other studies that consider SCF in elliptical holes and other types stress risers are also available in literature (Enab, 2014;Kumar et al, 2016;Jadvani et al, 2017b;Zhou and Fei, 2017).…”

PurposeThe purpose of this paper is to investigate the strain concentration factor in a central countersunk hole riveted in rectangular plates under uniaxial tension using finite element and response surface methods.Design/methodology/approachIn this work, ANSYS software was elected to create the finite element model of the present structure, execute the analysis and generate strain concentration factor (,) data. Response surface method was implemented to formulate a second order equation to precisely compute (,) based on the geometric and material parameters of the present problem.FindingsThe computations of this formula are accurate and in a great agreement with finite element analysis (FEA) data. This equation was further used for obtaining optimum hole and plate designs.Originality/valueAn optimum design of the countersunk hole and the plate that minimizes the (,) value was achieved and hence validated with FEA findings.
