Period fissioning and other instabilities of stressed elastic membranes
Under elastic membrane the shape of stretching two dimensional parameter space
2014/12/19
We study the shapes of elastic membranes under the simultaneous exertion of tensile and compressive forces when the translational symmetry along the tension direction is broken. We predict a multitude...
Elastic building blocks for confined sheets
Elastic thin sheet bending smooth constraint the stress distribution energy mechanical constraints
2014/12/19
We study the behavior of thin elastic sheets that are bent and strained under the influence of weak, smooth confinement. We show that the emerging shapes exhibit the coexistence of two types of domain...
Smooth Cascade of Wrinkles at the Edge of a Floating Elastic Film
Thin polymer film liquid uniaxial compression wrinkles wrinkles model capillary force
2014/12/18
An ultrathin polymer sheet floating on a fluid forms a periodic pattern of parallel wrinkles when subjected to uniaxial compression. The wave number of the wrinkle pattern increases sharply near the f...
Measurement of the Parity Violating Asymmetry in Elastic Electron Scattering off 208Pb
Jefferson Lab parity violating electron scattering scattering asymmetry neutron skin thickness
2014/11/20
The Lead Radius Experiment (PREX) was carried out in order to provide a model independent measurement of the RMS radius √ < r2 >of the neutron distribution in the 208Pb nucleus. The parity-violating s...
Swelling and Folding as Mechanisms of 3D Shape Formation in Thin Elastic Sheets
elasticity folding geometry origami swelling thin sheets
2014/11/20
We work with two different mechanisms to generate geometric frustration on thin elastic sheets; isotropic differential growth and folding. We describe how controlled growth and prescribing folding pat...

2011/7/21
The vector analyzing power has been measured for the elastic scattering of neutron-rich 6He from polarized protons at 71 MeV/nucleon making use of a newly constructed solid polarized proton target ope...
The neutral current elastic scattering of neutrinos on Carbon and $CH_2$ targets is computed using the relativistic distorted-wave impulse approximation with relativistic optical potential. Results fo...

2011/7/28
Abstract: In this paper we consider a sample of a linearly elastic heterogeneous composite in elastodynamic equilibrium and present universal theorems which provide lower bounds for the total elastic ...

Orientation dependence of the elastic instability on strained SiGe films
Orientation dependence elastic instability strained SiGe films
2010/11/23
At low strain, SiGe films on Si substrates undergo a continuous nucleationless morphological evolution known as the Asaro-Tiller-Grinfeld instability. We demonstrate experimentally that this instabili...

Parity-violating (PV) elastic electron-proton scattering measures Q-weak for the proton, QpW
. To extract QpW from data, all radiative corrections must be well-known. Recently, disagreement on the gZ...
We report resonant ultrasound spectroscopy (RUS), dilatometry/magnetostriction, magnetotransport,magnetization, speci c-heat, and 119Sn Mossbauer spectroscopy measurements on SnTe and Sn0:995Cr0:005T...
Note and calculations concerning elastic dilatancy in 2D glass-glass liquid foams
Note calculations
2010/11/17
When deformed, liquid foams tend to raise their liquid contents like immersed granular materials,a phenomenon called dilatancy. We have aready described a geometrical interpretation of elastic dilatan...

Elastic electronic properties Re2N in comparison
2010/11/23
Very recently, two new hexagonal rhenium sub-nitrides Re3N and Re2N, which belong to a rather rare group of known metal-rich (M/N > 1) nitrides of heavy 4d,5d metals, have been successfully synthesize...
