ASME-AMD Summer Meeting 2013: Dynamic Stability of Structural Systems

Dear Colleague:

The 2013 summer meeting of ASME Applied Mechanics Division will be held jointly with the Society of Engineering Science at Brown University, Providence, RI, July 28-31. We are pleased to invite you to a session on Dynamic Stability of Structural Systems, under the symposium on Instability in Solids and Structures that is being organized by the AMD Technical Committee.

Elasticity of rubber-like materials

In the notes on the general theory of finite deformation, we have left the free energy function unspecified. The notes here describe free energy function commonly used to describe the elasticity of rubber-like materials.  These notes are part of a course on advanced elasticity

Senior Research Scientist in hydraulic fracturing/geomechanics

CSIRO division of Earth Science and Resource Engineering is seeking a Senior Research Scientist in hydraulic fracturing/geomechanics. The position is located in Melbourne, Australia and the successful candidate will play a leading role in a world class hydraulic fracturing laboratory facility and in a hydraulic fracturing research team that integrates modelling with experimentation at laboratory and field scales.

Nonlinear geometric effects in mechanical bistable morphing structures

Bistable structures, exemplified
by the Venus flytrap and slap bracelets, can switch between different
functional shapes upon actuation, and have important applications in
mechanical/electro-mechanical devices ranging from bio-inspired robots to
deployable aeroplane wings. Despite numerous efforts in modeling such large
deformation of shell structures, the roles of mechanical and nonlinear geometric
effects on bistability remains elusive. Closely related, emerging challenges
include modeling the spontaneous curving and buckling of thin objects such as

Nanocomposite Electrical Generators....

A nanocomposite electrical generator composed of an array of zinc oxide nanowires is considered.
The electric potential distribution along zinc oxide nanowires is modeled using continuum
mechanics and Maxwell’s equations for the case of axial loading. A perturbation technique is used
for decoupling the constitutive equations. The governing differential equations are solved using a
finite difference method. It is shown that a gradient of electric potential exists along the axis of the
zinc oxide nanowires. Maximum and minimum values of electric potential exist at the extreme ends
along the nanowire length and have opposite signs. The positive and negative voltages are separated

Poroelastic problems

 

Hi everybody. My name is Alexander Lyapin. I am a second year postgraduate student of Southern Federal University, Russia, Rostov-on-Don, and I am working in the field of poroelasticity. The topic of my future dissertation is "Dynamic problems of poroelastic enviroments". The main problems in my dissertation are fundamental solutions and enviroments with cavities of common arbitary shape. I use different methods such as boundary integral equations method Fourie transformation method and some other.

Size effects on elasticity, yielding, and fracture of silver nanowires

This paper reports the quantitative measurement of a full spectrum of mechanical properties of fivefold twinned silver (Ag) nanowires (NWs), including Young’s modulus, yield strength, and ultimate tensile strength. In-situ tensile testing of Ag NWs with diameters between 34 and 130 nm was carried out inside a scanning electron microscope (SEM). Young’s modulus, yield strength, and ultimate tensile strength all increased as the NW diameter decreased.

Viscoelastic RVE for CNT Composites

Hi
all,

I am Mohammad Aramfard senior student of mechanical engineering and I joined this
great forum yesterday, so I am not very familiar with regulations and rules.Laughing

I am working on modeling CNT composites using cylindrical RVE and I found up to
now that there isn`t a viscoelastic RVE for representing behavior of these
composites.

New Generation CAE system for framed structures

Dear Colleagues,

I would be glad to present symbolic-numeric CAE system for frame structures analysis.

It will be available soon as Preview version for enthusiasts

The main features are:

Beam Equation

How can we derive dynamic beam equation from navier equation in elastodynamic? I tried with the displacement vector field:

u=-z*w(x,t)

v=0

w=w(x.t)

and put it in navier equation, but it does not work.

Continuity of traction vector

I am looking for a source which has a good explanation of the pill box argument to prove continuity of the traction vector. If you know of such a source (url, book etc) please let me know. 

Thanks,
