The mentioned reference is focused on an analytical method for modeling large deflections in compliant mechanisms, while this work presents a method of enhancing the tensile strength of lamina emergent joints by using double-layer materials. As compared to Ref. [19] which focuses on concepts and demonstrations, this work mainly focuses on analytical modeling of one design concept and provides finite element and experimental validations.
