Multiscale modeling of ductile-fiber-reinforced composites

The tensile strength and ductility of fiber-reinforced composites containing ductile metal fibers is studied using a multiscale approach and compared to the performance of an identical composite containing elastic fibers. A finite element model of stress r ...

Stiffness of Aligned Wood Fiber Composites: Effect of Microstructure and Phase Properties

Razvan Cristian Neagu

The effect of wood fiber anisotropy and their geometrical features on wood fiber composite stiffness is analyzed. An analytical model for an N-phase composite with orthotropic properties of constituents is developed and used. This model is a straightforwar ...

Part II: Fibroblasts preferentially migrate in the direction of principal strain

Matthias Lütolf, Jeffrey Alan Hubbell

A growing body of evidence suggests that the sensory information from the cytoskeleton and integrins may be responsible for guiding migration during mechano- and haptotaxis. However, the dual function of these subcellular structures as mechano-sensors and ...

Discontinuous Palladium Nanostructures for H2 Sensing

Jürgen Brugger, Luis Guillermo Villanueva Torrijo, Thomas Kiefer

Various top-down, bottom-up and hybrid fabrication routes of discontinuous palladium nano and mesostructures can be used for the fabrication of resistor based H2 sensing devices. 1-D, 2D, and 3-D structures can be achieved using appropriate material templa ...

Multi-scale plasticity modeling: Coupled discrete dislocation and continuum crystal plasticity

William Curtin

A hierarchical multi-scale model that couples a region of material described by discrete dislocation plasticity to a surrounding region described by conventional crystal plasticity is presented. The coupled model is aimed at capturing non-classical plastic ...

Damage evolution in coated cemented carbides under compressive contact loads

Maria-Simona Moldovan

This work deals principally with two important issues and their interrelation: the evolution of damage in coated cemented carbide tools used for cold forming, and the assessment of mechanical behavior of cemented carbides under compressive contact loads. D ...

Establishing stress-strain relationship for natural-stone masonry

Alix Grandjean

The conservation of historical monuments and especially natural stone masonry arch bridges is an issue which is becoming increasingly important. The prerequisite for any analysis of the load carrying capacity of such stonework is a precise knowledge of its ...

An X-ray absorption spectroscopy study of an oxide dispersion strengthened steel

Manuel Alexandre Pouchon, Wolfgang Hoffelner

Oxide dispersion strengthened (ODS) steels are being investigated as possible structural material for components of future nuclear power plants. The dispersoids in the matrix (yttria particles) serve as pinning points for moving dislocations, and thereby i ...

Permeability of deformable soft aggregated earth materials: From single pore to sample cross section

Dani Or

[1] Fluid flow in deformable porous media is of interest in many areas of hydrology, geophysics, and environmental engineering at scales ranging from individual pore to field scale. With increasing interest in pore-scale hydraulics, there is also the need ...
