Abstract
A computer-implemented method of generating one or more variable stiffness structures includes determining a thickness of a first portion of a variable stiffness structure; determining a pressure that is to be applied to a surface of the first portion; selecting a first predetermined value for a stiffness attribute based on the thickness of the first portion and the pressure; and generating a model of at least part of the variable stiffness structure that includes the first portion, wherein the first portion has the predetermined value for the stiffness attribute.
