Transverse orthotropic elastic moduli of bundled coated thin elliptical tubes

In-plane effective shear modulus of generalized circular honeycomb structures and bundled tubes in a diamond array structure

“…The present analysis generalizes the method adopted for evaluating moduli of coated tubes in square array [27]. In the referred work, Fourier coefficients were found by numerically inverting the set of equations obtained from the boundary conditions.…”
