Finite element and response surface methods were utilised to investigate the strain concentration factor-induced in isotropic rectangular plates with two identical countersunk rivet holes due to uniaxial tension. Besides, a simple and precise formula to compute the strain concentration factor (SεCF) is developed. In this investigation, the finite element model was constructed using ANSYS software and used to produce (SεCF) data. Additionally, the response surface method (RSM) was implemented to examine the influence of the problem geometric and material parameters on the SεCF. RSM combined with least square regression methods were engaged to formulate a simple and effective equation to mathematically compute stress concertation factor () value. This equation was consequently verified with finite element analysis (FEA) results. Lastly, an optimum plate and hole configuration than minimises the SεCF was suggested and hence recommended.
