Metal foams are a class of materials with immense potential. The complex topology in these lightweight systems is responsible for their outstanding mechanical and thermal properties. Furthermore, this the same reason why assessment metal challenging. While conventional analytical techniques provide useful data, modern-age technology allows to explore transfer great detail by building digital tw...

The use of metal foams as permanent cores in casting products is a promising strategy. It aims to improve the properties cast components by adding certain foam features (e.g., lightweight, high specific stiffness, impact energy/vibration absorption ability, and good acoustic insulation properties). eliminates steps removal, treatment, compulsory recycling for traditional temporary sand cores. H...

Due to their mechanical properties, metal foams are used in various fields. The aim of the present research is collect different studies about important properties foams, such as Young’s modulus, tensile and shear strength, relative density, etc. under loading. Gaps were identified methodological embodiments experiments due use standards, well calculation through mathematical relations shear, w...

The fatigue behavior of a cellular composite with an epoxy matrix and glass foam granules is analyzed and modeled by means of continuum damage mechanics. The investigated cellular composite is a particular type of composite foam, and is very similar to syntactic foams. In contrast to conventional syntactic foams constituted by hollow spherical particles (balloons), cellular glass, mineral, or m...

3D annealed SnO2/graphene sheet foams (ASGFs) are synthesized by in situ self-assembly of graphene sheets prepared by mild chemical reduction. L-ascorbyl acid is used to effectively reduce the SnO2 nanoparticles/graphene oxide colloidal solution and form the 3D conductive graphene networks. The annealing treatment contributes to the formation of the Sn-O-C bonds between the SnO2 nanoparticles a...

NiTi foams were created with a structure (32-36% open pores 70-400 microm in size) and mechanical properties (4-25 GPa stiffness, >1000 MPa compressive strength, >42% compressive ductility, and shape-memory strains up to 4%) useful for bone implant applications. A mixture of NiTi and NaCl powders was hot-isostatically pressed at 950 and 1065 degrees C and the NaCl phase was then dissolved in wa...

We herein present results from experimental investigations and new numerical methods for the investigation of fluid flow and heat transfer in cellular solids, in particular open cell metal foams. Results from a custom made test facility contribute to enlarge the public available database of open cell metal foams and serve for the validation of applied commercial and inhouse numerical methods.
