Deformation twinning mechanism in magnesium at the microscale: strain rate, temperature and orientation effects

The project aims to validate some recent theoretical developments on the deformation twinning nucleation mechanism in HCP metals through small-scale mechanic experiments. To this end, a systematic investigation of the mechanical response of pure magnesium ...

Large particle segregation in two-dimensional sheared granular flows

Christophe Ancey, Tomás Alfredo Trewhela Palacios

We studied the segregation of single large intruder particles in monodisperse granular materials. Experiments were carried out in a two-dimensional shear cell using different intruder and media diameters, whose quotient defined a size ratio R that ranged f ...

Basic creep of limestone-calcined clay cements: An experimental and numerical approach

Karen Scrivener, Julien Ston

This article presents a study on the creep properties of limestone calcined clay cement. A series of paste samples using limestone and calcined clays as replacement materials were tested under basic compressive creep. The ternary mixes showed a lower creep ...

Ductility, recovery and strain rate dependency of an acrylic structural adhesive

Thomas Keller, Anastasios Vassilopoulos, Myrsini Angelidi

The ductility and time-dependent recovery of a ductile acrylic adhesive were investigated in this work. The quasi-static true tensile and compressive strain behaviors were examined at different strain rates, taking large deformations into account. Yield st ...

ACMEG-TVP: A thermoviscoplastic constitutive model for geomaterials

Yafei Qiao

In this paper, a thermoviscoplastic constitutive model for geomaterials is presented. The model is formulated based on two aspects: (i) the nonstationary flow surface theory, which is used to describe the viscous behaviour of geomaterials, and (ii) the the ...
