Damping properties of the nucleus pulposus

Dominique Pioletti, Arne Christian Vogel

Background: The nucleus pulposus is extremely deformable and it is not uncommon to observe strain amplitudes as large as 12.5% in physiological loading conditions. It has been shown that the nucleus pulposus contributes to the damping properties of the int ...

Joachim Krieger

For the critical focusing wave equation

\square u=u^5

on

\mathbb{R}^{3+1}

in the radial case, we prove the existence of type II blow up solutions with scaling parameter

\lambda(t)=t^{-1\nu}

for all

\nu>0

. This extends the previous work by the autho ...

Simulation of the welding process of steel tube joints made of S355 and S690

Janna Krummenacker

Welding is an important joining method for the work with metals. During the welding process, the material is heated and deforms plastically which leads a change in microstructure in the heat affected zone, to complex residual stress distributions, and dist ...

Strain-rate behavior in tension of the tempered martensitic reduced activation steel Eurofer97

Philippe Spätig

The tensile properties of the high-chromium tempered martensitic reduced activation steel Eurofer97 were determined from tests carried out over a wide range of strain-rates on cylindrical specimens. The quasi-static tests were performed with a universal el ...

Time-Dependent Response of Ultra High Performance Fibre Reinforced Concrete (UHPFRC) under Low to High Tensile Stresses

Agnieszka Ewa Switek

Ultra High Performance Fibre Reinforced Concretes (UHPFRC) are characterised by high mechanical performance, extremely low permeability and tensile strain hardening. For structural applications, in composite structures they are very well adapted for reinfo ...

Finite element implementation of a kinetic model of dynamic strain aging in aluminum-magnesium alloys

William Curtin

Soare and Curtin (Acta Mater. 2008; 56:4091-4101, 4046-4061) have recently developed a model of dynamic strain aging in solute-strengthened alloys. Their constitutive law describes time-dependent solute strengthening using rate equations that can be calibr ...

Modelling the effect of temperature on crack onset strain of brittle coatings on polymer substrates

Yves Leterrier, Laure Dupuits Lalande, Judith Helen Waller

The effect of temperature on the crack onset strain (COS) of brittle coatings on polymer substrates was investigated through a series of temperature-controlled tensile tests carried out in situ under an optical microscope. It was observed that the failure ...

Influence of the meso-structure in dynamic fracture simulation of concrete under tensile loading

Jean-François Molinari, Leonardo Snozzi

We investigate the dynamic behavior of concrete in relation to its composition within a computational framework (FEM). Concrete is modeled using a meso-mechanical approach in which aggregates and mortar are represented explicitly. Both continuum phases are ...

Laminated Metal Composites by Infiltration

Andreas Mortensen, Andreas Rossoll, Jérôme Krebs, Arda Cetin, Alexandre Durussel

We show that steel-magnesium alloy laminated metal composites (LMCs) can be produced by gas pressure infiltration of a liquid magnesium alloy between layers of stacked dimpled steel sheets. Resulting LMCs are amenable to subsequent warm rolling. The LMCs a ...

Microstructure and mechanical properties of an ODS RAF steel fabricated by hot extrusion or hot isostatic pressing

Nadine Baluc, Zbigniew Oksiuta

Ingots of an oxide dispersion strengthened reduced activation ferritic steel with the Fe-14Cr-2W-0.3Ti-0.3Y(2)O(3) chemical composition (in wt.%) were synthesized by mechanical alloying of elemental powders with 0.3 wt.% Y2O3 particles in a planetary ball ...
