A new strain rate dependent continuum framework for Mg alloys

Magnesium (Mg) alloys have recently been put under the spotlight for their specific strength, the highest among structural metals. Although the mechanical behaviour of Mg alloys at quasi-static strain rates has been extensively modelled in the recent years ...

Bridging effects on Mixed Mode delamination: experiments and numerical simulation

Marco Borotto

Composite materials and, in particular, Carbon Fibre Reinforced Polymers (CFRP) have been well studied and developed in the past years due to their advanced mechanical characteristics. These materials are used in several different application fields, such ...

Eulerian theory of newtonian deformable lattices – dislocation and disclination charges in solids

Gérard Gremaud

This book lays methodically the foundations of an original approach of the solid lattices deformation using the Euler coordinates, and introduces in details the concept of tensor dislocation charges and tensor disclination charges within a lattice. This ne ...

Physics-based constitutive modelling for crystal plasticity finite element computation of cyclic plasticity in fatigue

Nicolò Grilli

Metal fatigue during cyclic loading puts an endurance limit on most of today's technology. It impacts the reliability of metallic components used for transportation, electronic devices and energy production because fatigue failure can occur without any app ...

Quantification of spatial variability for transverse elastic modulus of spruce wood

Thomas Keller, Anastasios Vassilopoulos, Alireza Farajzadeh Moshtaghin, Steffen Franke

Different factors such as age, location of timber within the tree, structural imperfections, load history such as wind and snow etc. can affect the material properties of timber. Consequently, there is a high variability in the mechanical properties which ...

Transparent dielectric elastomer actuator used as tunable optical grating

Herbert Shea, Samuel Rosset, Xiaobin Ji

In this work, a transparent dielectric elastomer actuator is integrated into a tunable transmission grating. A 13 micron-thick silicone membrane has been sandwiched between two 750 nanometer-thick transparent ionogel electrodes to fabricate a transparent d ...

Constitutive and numerical modeling of anisotropic quasi-brittle shales

Francesco Parisio

Understanding the hydro-mechanical behavior of shale is fundamental to assess the safety of deep geological nuclear repository sites. Several countries have adopted argillaceous formations as host geological media for the repository. In Switzerland, the ca ...

Approaches for suitable modelling and strength prediction of reinforced concrete slabs

Aurelio Muttoni, Miguel Fernández Ruiz, Raffaele Cantone, Beatrice Belletti

Despite the advances on the understanding and modelling of shear and punching shear failures, the application of actual design models to some stations remains still complex. In addition, other significant phenomena such as compressive membrane action and m ...

The statistical variability and length effects in the tensile transverse behavior of clear timber

Thomas Keller, Anastasios Vassilopoulos, Alireza Farajzadeh Moshtaghin, Steffen Franke

In this work, clear timber specimens of different lengths with a small cross-sectional area were cut in the transverse direction of timber boards and tested under tensile loading. Regularly positioned and randomly positioned specimens were cut from differe ...

Creep and stress relaxation of a FeMnSi-based shape memory alloy at low temperatures

Cyril Cayron, Christian Leinenbach

The creep and stress relaxation behavior of a Fe-17Mn-5Si-10Cr-4Ni-1(V,C) (wt%) shape memory alloy at low homologous temperatures (-45 degrees C < T < 50 degrees C) was systematically studied in stress and strain controlled tensile tests. At constant stres ...
