In FigureĀ 3-5, it can be seen that ESL theory is more suitable for moderately thick to very thin laminates, whereas layerwise theory is more suitable for moderately thin to very thick laminates. The selection of ESL theory for very thick laminates may give rise to incorrect transverse shear stresses whereas the selection of layerwise theory for very thin laminates may give rise to shear locking.
