Design exploration methodology for ultra thick laminated composites [PDF]

open access: yes, 2012
Existing test and analytical methods (theoretical and numerical) are normally restricted to thin laminate components, which cannot accurately represent the 3D stress state behaviour of the so called Ultra Thick Laminates (UTL) structures.
