Explosive fragmentation of Prince Rupert's drops leads to well-defined fragment sizes

Jean-François Molinari

Anyone who has ever broken a dish or a glass knows that the resulting fragments range from roughly the size of the object all the way down to indiscernibly small pieces: typical fragment size distributions of broken brittle materials follow a power law, an ...

Flexural behaviour of post-tensioned glass beams: Experimental and analytical study of three beam typologies

Alain Nussbaumer, Pieter Christian Louter, Jagoda Cupac

The concept of post-tensioned glass beams builds on the concrete analogy of the reinforced glass beams. By additionally prestressing the reinforcement in a post-tensioned system, a compressive pre-stress is applied on the glass, enhancing the initial fract ...

Ug-value and edge heat loss of triple glazed insulating glass units:A comparison between measured and declared values

Andreas Schueler, Anna Krammer

Triple glazed low-e coated insulating glass units with argon filling of five different suppliers on the European market with a declared thermal transmittance in the undisturbed centre of glass (Ug-value) of 0.6 W/m(2)K have been purchased from resellers an ...

Post-tensioning of glass beams: Analytical determination of the allowable pre-load

Alain Nussbaumer, Pieter Christian Louter, Jagoda Cupac

The effectiveness of post-tensioning in enhancing the fracture resistance of glass beams depends on the level of compressive pre-stress introduced at the glass edge surface that will in service be exposed to tensile stresses induced by bending. Maximum pre ...

Role of the electron-phonon coupling on the thermal boundary conductance of metal/diamond interfaces with nanometric interlayers

Ludger Weber, Gionata Schneider, Maïté Blank

Thermal boundary conductance (TBC) of the Ag/diamond and Au/diamond interfaces with a nanometer-thick interface layer of either nickel or molybdenum is measured by time domain thermoreflectance and modeled based on a 3-layer two-temperature model (3l-TTM). ...

Coatings with tailored electronic and optical properties for advanced glazing

Olivia Valérie Charlotte Bouvard

Modern envelope glazing relies on nanoscale coatings to meet a range of specific needs. Low emissivity coatings can improve the thermal performance of glazing thanks to a thin metallic film. However, the conductive nature of this layer leads to an attenuat ...

Passive diamagnetic contactless suspension rotor with electrostatic glass motor

Hannes Bleuler, Jin Zhou, Ryosuke Kan, Yuanping Xu

In this work, we introduce a newly developed passive and frictionless diamagnetic contactless suspension rotor with electrostatic glass motor. A 20 mm diameter disc-shaped rotor comprised of pyrolytic graphite with glass is fabricated. The rotor is diamagn ...

Non-contact femtosecond laser-based methods for investigating glass mechanics at small scales

Christos Edouardos Athanasiou

With the progress made in miniaturizing systems over the last decades, understanding materialsâ behavior at small scales has become a necessity. In this context, glass behavior has remained largely unknown, partly for technological reasons and partly due ...

Numerical analysis of fragmentation in tempered glass with parallel dynamic insertion of cohesive elements

Jean-François Molinari, Marco Vocialta, Mauro Corrado

Tempered glass panes are subjected to high eigenstresses that induce a state of compression along the surfaces and a state of tension in the inner part. Whenever a crack reaches the tensile region, it rapidly propagates and branches in all directions drive ...

Through-Glass Vias for Glass Interposers and MEMS Packaging Applications Fabricated Using Magnetic Assembly of Microscale Metal Wires

Göran Stemme, Mikhail Asiatici

A through-glass via (TGV) provides a vertical electrical connection through a glass substrate. TGVs are used in advanced packaging solutions, such as glass interposers and wafer-level packaging of microelectromechanical systems (MEMS). However, TGVs are ch ...
