Abstract
Full field tangential stress distribution in a uniaxially loaded composite circular cylindrical shell with various laminate sequences with reinforced square hole with rounded corners is achieved and good agreement is obtained with finite element results. Available solution for stress distribution in an infinite plate with square hole under axial load is suitably modified with unknown coefficients in the power series of hole shape parameter, ε and curvature parameter, β (orthotropic plate solution + trigonometric terms as a function of πβ2 /2). The reinforcement thickness for a desired target SCF value (preferably 50% reduction) and region of reinforcement over the shell surface w.r.t hole centre for any combination of hole size, shell thickness and radius are arrived at by an empirical relation based on numerical analysis. Solution for shell with reinforced square hole with β ≤ 0.25 is arrived at by an iterative technique and further expressed and validated for large size reinforced holes for β ≤ 2.0.
