Layout of Tileable Multistable Structures Using Topology Optimization approach, where each member is represented using a non-linear beam. A member is either hinged or fixed at either end and a rubber-like material is used to model the hinges. The optimization is implemented using a genetic algorithm. The methodology developed is illustrated with an example.

Topology Optimization of Dispersion Properties in Optical Fibresding the sensitivities of the dispersion coefficient is introduced, along with different constraints for confining the light to the centre of the fibre geometry. The modal analysis of the fibre geometries is carried out with a finite-difference approximation to the scalar Helmholtz wave equation. Th

Eigenfrequency and Buckling Optimization of Laminated Composite Shell Structures Using Discrete Matehe so-called Discrete Material Optimization (DMO) approach. The design optimization method is based on ideas from multi-phase topology optimization where the material stiffness is computed as a weighted sum of candidate materials, thus making it possible to solve discrete optimization problems using

Effect of Internal Length Scale on Optimal Topologies for Cosserat Continua stiffness is applied to two dimensional structural elements described in terms of micropolar (Cosserat) solids. The role of the characteristic length of bending on the optimal configurations is highlighted in the applications.
