Phase transformation induced distortions in red gold alloys

Margaux Nathalie Dominique Larcher

Red gold alloys owe their warm and attractive colour to the combination of gold and copper atoms. Thanks to their good mechanical properties and resistance to corrosion, red gold alloys are used in luxury industries as well as in dentistry. Around the equi ...

Morphomechanical Model Of The Torsional C-Looping In The Embryonic Heart

Alfio Quarteroni

Before septation processes shape its four chambers, the embryonic heart is a straight tube that spontaneously bends and twists breaking the left-right symmetry. In particular, the heart tube is subjected to a cell remodeling inducing ventral bending and de ...

Seed Dibbling Method for the Grow of High-Quality Diamond on GaN

Elison de Nazareth Matioli, Remco Franciscus Peter van Erp, Riyaz Mohammed Abdul Khadar, Reza Soleiman Zadeh Ardebili, Alessandro Floriduz, Mehdi Naamoun

The integration of diamond and GaN has been highly pursued for thermal management purposes as well as combining their exceptional complementary properties for power electronics applications and novel semiconductor heterostructures. However, the growth of d ...

A parametric neutron Bragg edge imaging study of additively manufactured samples treated by laser shock peening

Roland Logé, Christian Leinenbach, Nikola Kalentics

Laser powder bed fusion is an additive manufacturing technique extensively used for the production of metallic components. Despite this process has reached a status at which parts are produced with mechanical properties comparable to those from conventiona ...

Nondestructive characterization of laser powder bed fusion parts with neutron Bragg edge imaging

Roland Logé, Christian Leinenbach, Nikola Kalentics

Laser powder bed fusion is an efficient technique for additive manufacturing of metallic materials. The quality of the material produced depends on the optimization of a large range of build parameters and the complex thermo-mechanical build process is pro ...

Crack propagation speeds in weak snowpack layers

Johan Alexandre Philippe Gaume, Bertil Trottet, Grégoire Bobillier

For the release of a slab avalanche, crack propagation within a weak snowpack layer below a cohesive snow slab is required. As crack speed measurements can give insight into underlying processes, we analysed three crack propagation events that occurred in ...

Propagation of fluid driven fractures in transversely isotropic material

Fatima-Ezzahra Moukhtari

The propagation of fluid driven fractures is used in a number of industrial applications (well stimulation of unconventional reservoirs, development of deep geothermal systems) but also occurs naturally (magmatic dyke intrusion). While the mechanics of hyd ...

Multiaxial fatigue criteria for prestressed strengthening of steel connections

Alain Nussbaumer, Elyas Ghafoori, Masoud Motavalli, Hossein Heydarinouri

In this study, the high-cycle fatigue behavior of bridge connections subjected to distortion-induced loadings (generating multiaxial stresses) and strengthened with prestressed elements were experimentally investigated. Thereafter, appropriate critical pla ...
