Bringing casting to microfabrication: processing and deformation of microcastings

This work extends the range of pathways for the production of metallic microcomponents by downscaling metal casting. This is accomplished by using either of two different molding techniques, namely femtosecond laser micromachining or lithographic silicon m ...

On the compressive and bond strength of reinforced concrete as structural properties

Francesco Rafael Alberto Moccia

Traditionally, the concrete strength is measured on cubes or cylinders having normalized dimensions, suitable vibration and curing conditions and their strength is assessed in laboratory under fast loading rates. However, the in-situ strength of structural ...

The influence of casting position and disturbance induced by reinforcement on the structural concrete strength

Aurelio Muttoni, Miguel Fernández Ruiz, Francesco Rafael Alberto Moccia

It is well known that control specimens used to assess the concrete strength of new structures have different casting and curing conditions than those of actual structures. Notably, after pouring of the concrete and before its hardening, a number of phenom ...

Small-scale metal castings, small-scale metal/transparent composite structures and process to produce same

Andreas Mortensen, Yves Bellouard, Raphaël Charvet, Cyril Dénéréaz

The method comprises at least the following steps: - exposing a substrate to focused laser irradiation at a preselected series of locations that trace a subset of the substrate volume that is connected to the surface of the substrate; some subsets of subst ...

Effect of fiber orientation on the in-plane tensile response of UHPFRC reinforcement layers

Eugen Brühwiler, Emmanuel Denarié, Maléna Bastien Masse

The application on existing Reinforced Concrete (RC) slabs of cast-on site Ultra-High Performance Fiber Reinforced cement-based Composite UHPFRC) layers is a very efficient reinforcement technique, currently spreading. For the design of these tensile reinf ...

Structural Behavior of R-UHPFRC - RC Composite Slabs

Maléna Bastien Masse

The application on existing Reinforced Concrete (RC) slabs of cast-on-site Ultra-High Performance Fiber Reinforced cement-based Composite (UHPFRC) layers is an efficient reinforcement technique, currently spreading. The thin layer of UHPFRC, with or withou ...

Stress-Strain Predictions of Semisolid Al-Mg-Mn Alloys During Direct Chill Casting: Effects of Microstructure and Process Variables

Jean-Marie Drezet, André Phillion

The occurrence of hot tearing during the industrial direct chill (DC) casting process results in significant quality issues and a reduction in productivity. In order to investigate their occurrence, a new semisolid constitutive law (Phillion et al.) for AA ...

Prediction of Hot Tear Formation in Vertical DC Casting of Aluminum Billets Using a Granular Approach

Michel Rappaz, Jean-Marie Drezet, André Phillion, Meisam Sistaninia

A coupled hydromechanical granular model aimed at predicting hot tear formation and stress-strain behavior in metallic alloys during solidification is applied to the semicontinuous direct chill casting of aluminum alloy round billets. This granular model c ...

Heterogeneous material micro-transfer by ink-jet print assisted mould filling

Jürgen Brugger, Grégoire Maxime Smolik, Loïc Jacot-Descombes, Vaida Auzelyte

A novel combination of ink-jet printing (IJP) and micro-transfer moulding (μ-TM) for high-resolution, heterogeneous material microstructuring is demonstrated. First, IJP is used to accurately fill the micro-cavities in an elastomeric mould, thus avoiding t ...

Design and acceptability assessment of a new reversible orthosis

Jamie Paik

We present a new device aimed at being used for upper limb rehabilitation. Our main focus was to design a robot capable of working in both the passive mode (i.e. the robot shall be strong enough to generate human-like movements while guiding the weak arm o ...
