The role of energy dissipation of polymeric scaffolds in the mechanobiological modulation of chondrogenic expression

Dominique Pioletti, Philippe Abdel Sayed, Ulrike Kettenberger, Salim Elias Darwiche

Mechanical stimulation has been proposed to induce chondrogenesis in cell-seeded scaffold. However, the effects of mechanical stimuli on engineered cartilage may vary substantially between different scaffolds. This advocates for the need to identify an ove ...

Effect of Slab Stiffness on EBF Link Rotation Demands and Implications for Link Ultra Low-Cycle Fatigue Susceptibility

Albano António De Abreu E Presa De Castro E Sousa, Gary Scott Prinz

This study aims to quantify slab contributions in EBFs by investigating the dynamic performance of two 3-story EBF configurations with and without concrete slabs: one configuration having long (flexural yielding) links and the other having shorter (shear y ...

Non-rectangular RC walls: A review of experimental investigations

Katrin Beyer, Raluca-Tereza Constantin

When compared to tests on reinforced concrete (RC) walls with a rectangular or barbelled cross-section, only very few tests on RC walls with open cross-section exist. Most of these walls were subjected to unidirectional or bidirectional loading along one o ...

Influence of particle breakage on the dynamic compression responses of brittle granular materials

The dynamic compression responses of dry quartz sand are tested with a modified spilt Hopkinson pressure bar (MSHPB), and the quasi-static compression responses are tested for comparison with a material testing system. In the experiments, the axial stress- ...

Stress–strain analysis of a toric pipe for inner pressure loads

Anton Schleiss, David Ferràs Segura

This research aims to enhance the knowledge on stress–strain states of a coiled pipe used for Hydraulic transient experiments. The membrane theory of shells of revolution has been applied for the description of axial and circumferential strains while an in ...

On the influence of transgranular and intergranular failure mechanisms during dynamic loading of silicon nitride

Jean-François Molinari

Plane-strain tensile loading numerical simulations of dynamic crack propagation in silicon nitride microstructures are conducted. The strength and toughness are evaluated as a function of strain rate and microstructural parameters, including grain size and ...

Block loading fatigue of adhesively bonded pultruded GFRP joints

Thomas Keller, Anastasios Vassilopoulos, Roohollah Sarfaraz Khabbaz

The effect of loading sequence on the fatigue behavior of adhesively-bonded pultruded GFRP double-lap joints was experimentally investigated by applying different tensile and compressive block loading patterns. The observed failure modes were consistent wi ...

Experimental investigation of the fatigue behavior of adhesively-bonded pultruded GFRP joints under different load ratios

Thomas Keller, Anastasios Vassilopoulos, Roohollah Sarfaraz Khabbaz

The fatigue response of adhesively-bonded pultruded GFRP double-lap joints was investigated under different loading patterns and experimental results were obtained for three different applied load ratios: R = 0.1, R = 10, and R = -1. The fatigue life of th ...

High-speed internal strain measurements in composite structures under dynamic load using embedded FBG sensors

John Botsis, Joël Cugnoni, Dragan Coric, Jeannot Frieden

Internal strain measurements in cross-ply carbon-epoxy composite plates under dynamic loads are carried out using embedded FBG sensors. The principle of the FBG interrogation is based on intensity demodulation achieved via a Fabry-Perot filter. To account ...
