Abstract

An analytical tool is developed using conformal mapping and the complex variable method for determining the Stress Resultant Concentration Factor (SRCF) in an infinite plate with a circular or elliptical hole. This tool is validated against Finite Element Analysis (FEA). A population space of 305 laminates is generated by stacking uni-directional Carbon Fibre Reinforced Polymer (CFRP) material at various orientations covering a wide spectrum of homogenised stiffness values. The analytical approach is then used to study the effect(s) of loading conditions, stacking sequences and laminate homogenised stiffness values on the SRCF at the edge of a circular hole.
