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...

Both experimental and numerical studies have shown that the crack-bridging is one of the most significant mechanism contributing to the fracture toughness of natural materials like nacre and bone. This study aims to explore if additive manufactured lattice structures can be used to bridge fatigue cracks as well, thereby improving the fracture...

Powder bed fusion (PBF) is a widely used metal additive manufacturing method where a part is built with almost no limitation on its geometrical layout. However, parts built by PBF typically suffer from distortions and residual stresses which depend on the PBF processing conditions and the geometrical layout of the part. In order to investigate...

The heat fluxes in (liquid) rocket engines can go up to high values and they need active cooling to prevent the chamber wall from failing. Transpiration cooling is identified as a way to achieve lower wall temperatures than commonly used regenerative cooling and regenerative cooling with additional film cooling (referred to as film cooling from...

Additive manufacturing allows material structuring, supporting the fabrication of multiple-level structures or metamaterials. Through the lens of classical stress reduction, nature’s cellular solid structures feature stress-homogenizing nodal topologies. Avian long bones are an example. Research into the mechanics of open cell cellular solids...

Catamarans are popular in the offshore sector as they combine good transverse stability and ample deck space with low wave resistance. However, their slender hull shape results in low restoring qualities in heave and pitch motions. The large motions in rough weather can often result in water impacting the underside of the deck connecting the two...
