A Theoretical Model to Study the Influence of Tow-drop Areas on the Stiffness and Strength of Variable-stiffness Laminates (2009, methodology): “This concept is shared by the research of Tatting [2], Gürdal [4], Jegley [5], Wu [6,7], Blom [10,11], and Lopes [8,9].”
Initial post-buckling of variable-stiffness curved panels (2014, methodology): “…to buckling optimisation, it has also been shown that VAT laminates can be used to delay first ply failure of plates under compression (Lopes et al., 2007); tune the fundamental frequency of shells (Blom et al., 2008) and increase global structural stiffness of cylindrical shells (Wu, 2008).”
