Isogeometric Analysis of Lattice Structures Having Compression-Twist Coupled Deformation

Year: 2021

Type: article

Abstract: We utilized the isogeometric analysis (IGA) method that uses NURBS basis functions in CAD systems, to account for the geometric exactness of a geometrically exact beam deformation, on a new type of metamaterial, twist-translation coupled structure showing a large twist angle.A two-dimensional unit cell structure was embedded in a cylindrical wall, using free-form deformation and an appropriate interpolation scheme.A parametric study on the effects of the dimensions of the cylinder and the number of cells, on the twisting angle was performed.Furthermore, the mechanism of the twist-translation coupled metamaterial was explored through numerical examples.
