The use of hat-shaped specimens for dynamic shear testing (2008)

Peirs, Jan, Verleysen, Patricia, Degrieck, Joris

In the last decades, specimens with the hat-shaped geometry have been used to study materials with respect to their shear behaviour including strain localization and adiabatic shear banding (ASB)....

Evaluation of the static stress-strain behaviour of phosphorus alloyed and titanium micro-alloyed TRIP steels (2008)

Bouquerel, Jeremy, Verbeken, Kim, Krizan, D, Barbe, L, Verleysen, Patricia, Houbaert, Yvan

A considerable research effort has been done in the field of cold rolled TRIP steels submitted to a two-step annealing cycle. After annealing, these steels contain retained austenite, which offers...

Influence of specimen geometry on split Hopkinson tensile bar tests on sheet materials (2008)

Verleysen, Patricia, Degrieck, Joris, Verstraete, Tom, Van Slycken, Joost

In recent years numerous studies on the high strain rate behaviour of sheet materials using split Hopkinson tensile bar set-ups have been reported in literature. For these experiments mostly...

Optimized calculation of high strain rate stress-strain curves (2008)

Verleysen, Patricia, Degrieck, Joris

The knowledge and understanding of high strain rate material behaviour have become increasingly important. For the dynamic characterization of materials very often split Hopkinson bar experiments are...

EFFECTS OF COMPOSITION, TEMPERATURE AND STRAIN RATE ON THE MECHANICAL BEHAVIOR OF HIGH-ALLOYED MANGANESE STEELS (2008)

Curtze, Sven, Kuokkala, Veli-Tapani, Hokka, Mikko, Peura, Pasi, Verleysen, Patricia

Due to the high manganese content and additions of aluminum, silicon, and possibly other alloying elements, TWIP steels possess a stacking fault energy that favors twinning as the predominant...

SIMULATION OF THE STATIC MECHANICAL BEHAVIOUR OF TRIP STEELS BY MICRO-MECHANICAL MODELLING (2008)

Bouquerel, Jeremie, Verbeken, Kim, Verleysen, Patricia, Houbaert, Yvan

TRIP (TRansformation-Induced Plasticity) steels display a composite behaviour originating from the different constituent phases present in these steels: polygonal ferrite, bainitic ferrite, and...

Microstructure and mechanical properties of Fe-cr model alloys and high Cr steels under neutron irradiation (2007)

Matijasevic, Milena, Al Mazouzi, Abderrahim, Verleysen, Patricia

In the 1950s, the 9-12Cr steels with low Carbon (max 0.1%) have been developed for their high creep-rupture strength combined with good oxidation and corrosion resistance at elevated temperatures and...
