The topology optimization of a compliant variable-camber morphing wing

In conventional aircrafts, lift control is achieved by using flap systems. It would be beneficial if flap systems could be replaced by a variable-camber morphing wing. It has been shown that variable-camber morphing wings can significantly improve the aerodynamic performance of the aircraft due to the smoothness of the surface, making it...

Topology Optimization for 4D-Printed Structures

In recent developments in the field of multi-material additive manufacturing, differences in material properties are exploited to create printed shape memory structures, which are referred to as 4D-printed structures. New printing techniques allow for the introduction of prestresses in the specimen during manufacturing. This research focuses on...

Additive manufacturing of locally self-supporting compliant mechanisms: Experimental characterization and topology optimization for successful metal 3D printing

The manufacturing freedom of additive manufacturing, and design freedom of topology optimization have proven to be a fruitful combination in creating and manufacturing designs. While research into applications of metal additive manufacturing has advanced from rapid prototyping to end-use components, metal additive manufacturing of compliant...

Mechanical Metamaterials by Topology Optimization

Auxetic materials exhibit material properties, which are usually not seen in nature. This type of materials belong to the class of mechanical metamaterials and can be used for e.g. energy absorption, cloaking of objects, shape morphing applications and the design of fiber-reinforced composites. They exhibit a negative Poisson’s value and derive...
