In situ characterization of a high work hardening Ti-6Al-4V prepared by electron beam melting

Helena Van Swygenhoven, Karl Alan Sofinowski, Nicola Casati

A multi-phase Ti-6Al-4V prepared by electron beam melting and thermal post treatments has been shown to exhibit increased strength and ductility over standard wrought or hot isostatic pressed Ti-6-Al-4V. The mechanical improvements are due to a prolonged, ...

Load history effects in fibre-reinforced polymer composite materials

Abdolvahid Movahedirad

Today, it is widely accepted that fatigue is one of the most common failure mechanisms in structural components, and pure static failure is rarely observed. Engineering structures are subjected to complex mechanical fatigue loading histories, which cause d ...

Thermal activation parameters of plastic flow reveal deformation mechanisms in the CrMnFeCoNi high-entropy alloy

Joël Bonneville, William Curtin, Céline Varvenne

To reveal the operating mechanisms of plastic deformation in an FCC high-entropy alloy, the activation volumes in CrMnFeCoNi have been measured as a function of plastic strain and temperature between 77 K and 423 K using repeated load relaxation experiment ...

Microstructure and flow stress evolution during hot deformation of 304L austenitic stainless steel in variable thermomechanical conditions

Roland Logé, Ke Huang

Most of industrial hot deformation processes are performed in variable conditions where the strain rate and/or deformation temperature are not constant. In this work, hot compression tests in both constant and varying strain rate conditions were performed ...

Learning nuisances to track pedestrians in autonomous vehicles

Alexandre Massoud Alahi, George Adaimi

Autonomous vehicles rely on an accurate perception module. One of the fundamental challenges is to efficiently track pedestrians surrounding a vehicle to anticipate risky situations. Over the past decades, researchers have formulated the tracking problem a ...

Reinforcing Civil Engineering Curricula With Courses Including Project-Based Software Applications

Gerard Guell Bartrina

Civil engineering (CE) is one of the broadest engineering fields, if not the most, and requires undergraduate students to be exposed to a variety of topics; each can be easily recognized as a major in its own. Establishing a successful curriculum is a majo ...

Hot deformation of a Fe-Mn-Al-C steel susceptible of κ-carbide precipitation

Roland Logé, Oscar Zambrano Zambrano

The mechanical properties of Fe-Mn-Al-C steel are significantly enhanced after κ-carbide precipitation via aging; however, most aging treatments are energy demanding because they require relatively high temperatures and extended holding times. This researc ...

Method and Device for Implementing Laser Shock Peening or Warm Laser Shock Peening During Selective Laser Melting

Eric Boillat, Roland Logé, Nikola Kalentics

A method for manufacturing an object including the steps of forming layers by adding successive layers of material to form the object by selective laser melting (SLM), and inducing plastic deformation and residual stress into solidified material of at leas ...

Flexural quasi-static behaviour of UHPFRC and R-UHPFRC circular slab specimens

Eugen Brühwiler, Xiujiang Shen

This paper investigates experimentally and numerically the biaxial flexural behaviour of thin circular slab specimens made of Ultra High Performance Fibre Reinforced Cementitious Composite (UHPFRC). The circular slab specimens represent an external tensile ...

Elevated temperature, micro-compression transient plasticity tests. on nanocrystalline Palladium-Gold: Probing activation parameters at the lower limit of crystallinity

Stefano Mischler, Johann Michler, Xavier Maeder

In this study, we probe the activation parameters and time-dependent plastic behavior of a nano crystalline Palladium-Gold alloy by means of elevated temperature micropillar compression experiments. All tests were conducted on a stable, displacement-contro ...

Semi-Rigid Moment-Resisting Behavior of Multiple Tab-and-Slot Joint for Freeform Timber Plate Structures

Stéphane Nicolas Roche

Historically based on the transfer of ancestral know-how, the art of carpentry changed considerably at the beginning of the 21st century with the arrival on the market of engineered wood products (EWP) and computer numerically controlled machines (CNC). Th ...
