Recycled Glass Fiber Composites from Wind Turbine Waste for 3D Printing Feedstock: Effects of Fiber Content and Interface on Mechanical Performance

This research validates the viability of a recycling and reusing process for end-of-life glass fiber reinforced wind turbine blades. Short glass fibers from scrap turbine blades are reclaimed and mixed with polylactic acid (PLA) through a double extrusion ...

Mechanical properties of replicated cellular Zn and Zn1.5Mg in uniaxial compression

Andreas Mortensen, Ludger Weber, Karel Lietaert

We present here a study of the mechanical behavior of cellular Zn and Zn1.5Mg with densities between 11.9 and 24.5%, produced by replication processing using NaCl as a spaceholder. Cellular Zn and Zn1.5Mg deform homogeneously during quasi-static compressio ...

Experimental push-out investigation on the in-plane force-deformation behavior of integrally-attached timber Through-Tenon joints

Yves Weinand, Aryan Rezaei Rad, Henry V. Burton

Spurred by developments in digital fabrication, there has been an increase in the application of the Integral Mechanical Attachment (IMA) technique in timber plate structures. Despite its increase in popularity, there have been very few systematic investig ...

Periodic cellular aluminum structures for space applications : from casting to additive manufacturing

Florian Thibaut Gallien

Mass is one of the crucial parameters for hardware that has to be placed in Earth orbit. Due to its harsh environment, a material with highest specific properties is desired to achieve space missions. The rise and development of new technologies, such as a ...

The effective stiffness of modern unreinforced masonry walls

Katrin Beyer, Bastian Valentin Wilding

Code design of unreinforced masonry (URM) buildings is based on elastic anal-ysis, which requires as input parameter the effective stiffness of URM walls. Eurocode estimates the effective stiffness as 50% of the gross sectional elastic stiffness, but compa ...

Micro-mechanical finite element modeling for in-plane behavior of historical masonry

Shenghan Zhang

Seismic assessment of unreinforced masonry structures remains a challenge. This dissertation investigates the in-plane behavior of historical masonry elements and proposes an advanced simulation method based on the cohesive zone model (CZM) in a finite ele ...

Anisotropic behaviour of Opalinus Clay through consolidated and drained triaxial testing in saturated conditions

Lyesse Laloui, Alessio Ferrari, Valentina Favero

This paper investigates the anisotropic hydro-mechanical behaviour of Opalinus Clay shale, the host material currently being considered for the construction of a nuclear waste repository in Switzerland. Consolidated and drained triaxial tests on Opalinus C ...

Elastic behavior of partially saturated gas shales during unloading - reloading cycles in uniaxial compression

Lyesse Laloui, Alessio Ferrari, Alberto Minardi

Elastic properties of gas shales are of utmost importance for the exploitation of shale gas reservoirs. Static elastic properties are usually measured by performing unloading-reloading cycles in uniaxial or triaxial compressive tests. The response of gas s ...

Mechanical properties of MC multimetallic carbides in steel

Lionel Michelet

Carbides constitute a class of materials used for many applications, where excellent mechanical properties, such as stiffness, hardness and fracture toughness, are required. The machining industry is a typical example where carbide are crucial materials. W ...

Nonlinear elastic response of partially saturated gas shales in uniaxial compression

Lyesse Laloui, Alessio Ferrari, Alberto Minardi

Elastic properties of gas shales are fundamental for the geomechanical characterization of unconventional reservoirs. Due to the presence of microcracks, a non-linear elastic behaviour with hysteresis is usually exhibited when gas shales are subjected to u ...
