Tensile response of UHPFRC under very low strain rates and low temperatures

Emmanuel Denarié, Mohamed Abdul Hafiz

This paper addresses the uniaxial tensile response of Strain Hardening Ultra High-Performance Fiber Reinforced Concretes (SH-UHPFRC) subjected to very low strain rates and low temperatures. The influence of four different strain rates; 1 × 10−5, 1 × 10−7, ...

Characterization, mechanical properties and dimensional accuracy of a Zr-based bulk metallic glass manufactured via laser powder-bed fusion

Roland Logé, Steven Van Petegem, Jamasp Jhabvala, Antonia Neels, Efthymios Polatidis, Annapaola Parrilli, Güven Kurtuldu, Navid Sohrabi

Bulk metallic glasses (BMGs) are high-strength, highly elastic materials due to their disordered atomic structure. Because BMGs require sufficiently high cooling rates to bypass crystallization, laser-based additive manufacturing (AM) methods have recently ...
