Frame structure topology optimization with extended flexible joints
(English)Manuscript (preprint) (Other academic)
This paper describes a joint formulation for beam copology optimization with flexible joints. Joints are important structural elements for stiffness and by including them in the topology optimizing problem joints will get the right stiffness. The joints are modelled by an assembly of more generic 2-joints, which have the ability to have different stiffness in different directions. This will lead to that unnecessary stiffness components are found and simpler joints may be constructed. The paper also describes a way to find stiffness values for the 2-joints and some examples will show the functionality of the joints.
