Abstract : The main aim of this paper is to determine the most critical geometrical parameters of dent, out of two geometrical parameters considered namely extent of dent and Dent Depth (DD). Extent of dent can be of any shape but for simplicity it is taken as corner rounded square shape and the measure for this shape is taken as Dent Side Length (DSL). In order to accommodate these two parameters simultaneously, FE models of thin plate with centrally located dent of thin plate are generated by varying the Dent Side Length (DSL) and Dent Depth (DD). These generated FE models are analyzed using static nonlinear FE analysis module of ANSYS including both geometrical and material non-linearities to determine the ultimate strength of the dented thin plates. Non-linear response surface regression analysis is carried out to fit response surface for ultimate strengths which are obtained from FE numerical analysis results taking the DSL and DD as input variables. From the regression analysis, it is found that Dent Depth is more dominant factor than extent of dent. Keywords- Dent – Ultimate Strength Ratio (USR), Dent Depth (DD) - Extent of Depth – Non Linear FEA.
