Optimal design of 3D beams and lattice structures


Our latest article on "Isogeometric sizing and shape optimization of 3D beams and lattice structures at large deformations" was just published in the journal "Structural and Multidisciplinary Optimization".

This work integrates the isogeometric collocation methods that we have developed in recent years for the discretization and design optimization of geometrically exact 3D beams into a holistic framework. By using spline representations for the initial configuration, the kinematic unknowns, and the design variables, here the initial the centerline curve and cross-sectional parameters of the beams, shape and sizing of 3D beams and complex lattice structures subject to large deformations can be optimized simultaneously.
