WebMar 1, 2024 · Introduction. Moderately thick beams, plates and shells or laminated composites are widely used for engineering structures in aircraft, automotive, shipbuilding, and other industries, and a vast amount of shear deformable theories has been presented to date involving higher-order shear deformation theories because such structures have a … WebClassical Beam Theory. In relation to the classical beam theory, the distribution of shear stress along the thickness of the sample is a parabolic function, which is equivalent to the neutral axis where it is highest and then decreases to zero at the tensile and compressive profile.
