WebWhat is more, the Kirchhoff–Love shell theory is applicable to thin shell structures with R / t > 20, where R is the radius of curvature of the surface and t is the thickness of the shell. However, for the analysis of thick shells, RM shell theory was found to be more accurate than KL theory because RM shell theory considers the transverse shear deformation, … WebAfter considering CNS as an equivalent shell, uniformly distributed springs along each boundary are added to simulate the resultant forces in that boundary condition. The equations of motion are derived based on First Order Shear Deformation Theory (FSDT) by considering Kirchhoff-Love assumptions.
