On the question of the sign of size effects in the elastic behavior of foams
Stephan Kirchhof, Alfons Ams, Geralf Hütter
Due to their good ratio of stiffness and strength to weight, foam materials find use in lightweight engineering. Though, in many applications like structural bending or tension, th…
Influence of Topology and Porosity on Size Effects in Stripes of Cellular Material with Honeycomb Structure under Shear, Tension and Bending
Rinh Dinh Pham, Geralf Hütter
Cellular solids are known to exhibit size effects, i.e., differences in the apparent effective elastic moduli, when the specimen size becomes comparable to the cell size. The prese…
A hybrid approach to simulate the homogenized irreversible elastic-plastic deformations and damage of foams by neural networks
Christoph Settgast, Geralf Hütter, Meinhard Kuna +1
Classically, the constitutive behavior of materials is described either phenomenologically, or by homogenization approaches. Phenomenological approaches are computationally very ef…
Kinematics and constitutive relations in the stress-gradient theory: interpretation by homogenization
Geralf Hütter, Karam Sab, Samuel Forest
The stress-gradient theory has a third order tensor as kinematic degree of freedom, which is work-conjugate to the stress gradient. This tensor was called micro-displacements just…
