An unload-induced direct-shear model for granular gouge friction in rock discontinuities

The experimental study introduces an unload-induced direct-shear model to investigate the frictional slip of a layer of simulated granular gouges induced by the combination of a decreasing normal stress and a constant shear stress. A frictional equilibrium ...

On the load-bearing efficiency of open-cell foams: A comparison of two architectures related to two processes

Andreas Mortensen, Andreas Rossoll

Using a simple beam element, this study estimates the elastic stiffness of two isotropic open-cell foam architectures that approximate, respectively, the space between tightly packed fluid bubbles and that defined between densified solid particles, and fin ...

Variable stiffness material based on rigid low-melting-point-alloy-microstructures embedded in soft poly(dimethylsiloxane) (PDMS)

Dario Floreano, Bryan Edward Schubert

Materials with controllable stiffness are of great interest to many fields, including medicine and robotics. In this paper we develop a new type of variable stiffness material based on the combination of a rigid low-melting-point-alloy (LMPA) microstructur ...

Exact geometric theory of dendronized polymer dynamics

Tudor Ratiu, François Gay-Balmaz

Dendronized polymers consist of an elastic backbone with a set of iterated branch structures (dendrimers) attached at every base point of the backbone. The conformations of such molecules depend on the elastic deformation of the backbone and the branches, ...

Measuring the mesh size of hydrogels

Mohamadreza Nassajian Moghadam

Hydrogels are cross-linked, water-swollen polymer networks that are widely used as a biomaterial. Because of high amount of water, they are mechanically poor and soft. This aspect limits their applications. The suitability of hydrogels as biomedical materi ...

Comparison of shape parametrization techniques for fluid-structure interaction problems

Davide Forti

This master thesis describes the development in the framework of Fluid- Structure Interaction (FSI) problems of an efficient and flexible technique treating the fluid-structure interface and mesh motion problems. The main idea is to build, through a new hi ...

Stored elastic energy in aluminium alloy AA 6063 billets: residual stress measurements and thermomechanical modelling

Jean-Marie Drezet

Stress relief treatment before machining and sawing aluminium direct chill cast products is required to avoid uncontrolled distortion, crack formation and significant safety concerns due to the presence of thermally induced residual stresses created during ...

Grain boundary relaxation and grain growth in 18-carat yellow gold alloy

Daniele Mari, Robert Schaller, Iva Tkalcec Vâju

A high-temperature anelastic relaxation peak in the mechanical loss spectrum of 18-carat yellow gold polycrystals is analysed and interpreted as due to grain boundary sliding accommodated predominantly by elastic deformation of the grains. The characterist ...

Understanding and Modeling of Grain Boundary Pinning in Inconel 718

Roland Logé

The microstructure stability during δ sub-solvus annealing was investigated in Inconel 718 alloy. A reference dynamically recrystallized microstructure was produced through thermomechanical processing (torsion). The reference microstructure evolution durin ...

Exciton-assisted optomechanics with suspended carbon nanotubes

Christophe Marcel Georges Galland

We propose a framework for inducing strong optomechanical effects in a suspended carbon nanotube based on deformation potential (DP) exciton–phonon coupling. The excitons are conﬁned using an inhomogeneous axial electric ﬁeld which generates optically acti ...
