Exploration of auxetics materials in sport

Thibault Antoine Marie Joseph Ghesquière-Diérickx, Nicolas Tireford

A special property of auxetic materials is their negative Poisson’s ratio : this material shortens or lengthen in all directions when subjected respectively to a compressive or tensile force. This unusual characteristic opens up new perspectives in many fi ...

Influence of low curing temperatures on the tensile response of low clinker Strain Hardening UHPFRC under full restraint

Emmanuel Denarié, Mohamed Abdul Hafiz

The tensile response of strain hardening UHPFRC under full restraint, subjected to curing temperatures of 20 °C, 10 °C, 5 °C, was investigated for two types of mixes with silica fume; Mix I with pure type I cement and Mix II with 50% replacement of cement ...

Biaxial flexural response of Strain-Hardening UHPFRC circular slab elements

Eugen Brühwiler, Xiujiang Shen, Wanghu Peng

The biaxial flexural response of strain-hardening UHPFRC circular slab element is investigated experimentally and analytically using the ring-on-ring test. The Digital Image Correlation (DIC) technology is applied to capture the 3D full-field of strain and ...

Mechanical properties of a balsa wood veneer structural sandwich core material

Thomas Keller, Anastasios Vassilopoulos, Niloufar Vahedi

Balsa wood is an appropriate core material for structural sandwich applications due to its high strength- and stiffness-to-weight ratios. However, the mechanical properties vary considerably owing to the inherent scattering of natural wood materials. One a ...

Joining of Oxide Dispersion-Strengthened Steel Using Spark Plasma Sintering

Cyril Cayron

Difficulties with joining oxide dispersion-strengthened (ODS) steels using classical welding processes have led to the development of alternative joining techniques such as spark plasma sintering (SPS). SPS, which is classically employed for performing sin ...
