Strained crystalline nanomechanical resonators with quality factors above 10 billion

Tobias Kippenberg, Alberto Beccari, Nils Johan Engelsen, Sergey Fedorov

In strained mechanical resonators, the concurrence of tensile stress and geometric nonlinearity dramatically reduces dissipation. This phenomenon, called dissipation dilution, is employed in mirror suspensions of gravitational-wave interferometers and at t ...

Tensile viscous response of Strain Hardening UHPFRC under high restraint and isothermal conditions

Emmanuel Denarié, Mohamed Abdul Hafiz

Strain Hardening Ultra High Performance Fiber Reinforced Concretes (SH-UHPFRC) have a high elastic limit (around 10 MPa) and high tensile strength (upto 20 MPa) and exhibit significant strain hardening (1 to 4 %) under tensile loads. These appealing featur ...

Experimental Study of Tensile Response of Strain Hardening UHPFRC at Early Age

Emmanuel Denarié, Mohamed Abdul Hafiz

Strain Hardening Ultra High Performance Fibre Reinforced Concrete (SH-UHPFRC), has a high tensile strength (over 10 MPa) and exhibit significant strain hardening (several parts per thousand) under tensile loads. These appealing features make it a suitable ...

Deformation behavior of nanoporous polycrystalline silver. Part I: Microstructure and mechanical properties

Helena Van Swygenhoven, Steven Van Petegem

This work reports on the microstructure and mechanical properties of porous silver films produced with different sintering parameters. The microstructure is investigated by high-resolution ptychographic Xray computed tomography and scanning electron micros ...

Numerical simulation of instability of thin reinforced concrete walls using beam elements under tension-compression

Katrin Beyer, João Saraiva Esteves Pacheco de Almeida, Angelica Rosso

The increasing demand for housing in Colombia and several neighboring countries, together with the large relative cost of the materials, has prompted city administrations to build thin reinforced concrete (RC) wall buildings with a single layer of reinforc ...
