Piecewise smooth systems near a co-dimension 2 discontinuity manifold: can one say what should happen?

, 2015
We consider a piecewise smooth system in the neighborhood of a co-dimension 2 discontinuity manifold $\Sigma$. Within the class of Filippov solutions, if $\Sigma$ is attractive, one should expect solution trajectories to slide on $\Sigma$.

Magnetic Phase Diagram of GdNi2B2C: Two-ion Magnetoelasticity and Anisotropic Exchange Couplings

, 2003
Extensive magnetization and magnetostriction measurements were carried out on a single crystal of GdNi2B2C along the main tetragonal axes. Within the paramagnetic phase, the magnetic and strain susceptibilities revealed a weak anisotropy in the exchange ...

Experimental and numerical characterizations of nano-indentation responses of low viscosity and high viscosity bone cements

Forces in Mechanics
The present work involves experimentally determining the nano-mechanical properties (elastic modulus, hardness, plasticity index, and recovery resistance) of low viscosity (LV) and high viscosity (HV) Poly (methyl methacrylate) (PMMA) bone cement from ...

Fermionic functional renormalization group for first-order phase transitions: a mean-field model

, 2006
First-order phase transitions in many-fermion systems are not detected in the susceptibility analysis of common renormalization-group (RG) approaches. Here we introduce a counterterm technique within the functional renormalization-group (fRG) formalism ...

Seismic analyses of a R/C building: study of a retrofitting solution [PDF]

, 2000
The preliminary experimental results from the tests on a 4-storey R/C frame structure are presented and discussed. The full-scale model is representative of the common practice of 40~50 years ago in most south European countries.

Weak ferromagnetism and internal magnetoelectric effect in LiFeP$_2$O$_7$

, 2012
The magnetic, thermodynamic, and pyroelectric properties of LiFeP$_2$O$_7$ single crystals are investigated with emphasis on the magnetoelectric interaction of the electrical polarization with the magnetic order parameter.

Hysteretic beam element with degrading bouc-wen models [PDF]

, 2013
In this work a beam element based on the finite element method, suitable for the inelastic dynamic analysis of structures is presented. The hysteretic beam element proposed by Triantafyllou and Koumousis [1] is extended to account for stiffness ...
