2016 ASME IMECE Call for Papers: Track 12-15 Failure and Fracture of Additively Manufactured Materials

Additive manufacturing or commonly known as 3D printing is a manufacturing technique that builds 3D objects by adding materials layer-by-layer.

Three year OCE Postdoctoral Fellowship in computational nanotechnology

Applications are invited for a three year OCE Postdoctoral Fellowship in computational nanotechnology, working with scientists from the Virtual Nanoscience Laboratory in the CSIRO Materials Science and Engineering division at Clayton, in Australia. The successful applicant will work be involved in predicting the material properties for optimal nanodiamond-based drug delivery systems, in collaboration with a multi-national interdisciplinary team.

Why Griffith's Law of fracture does not hold at the nanoscale

We know from fracture mechanics theories that fracture instability in a perfectly brittle material occurs when energy release rate (G) becomes equal or more than two times the surface energy (γ) of that material. The value of G = 2γ is known as fracture toughness Gc. This is the classical Griffith criteria of brittle fracture. Experimentally, however, we know that plasticity becomes eminent for most materials and this criteria does not work.

Effect of Surface Morphology on the Stability of Thin Nanostructures

We have recently studied the atomic scale structural stability of
freestanding wavy gold (Au) nanofilms using molecular dynamics
simulations. In recent years, wavy or patterned structurs have shown great promise for applications in
various emerging technologies including fuel cells
engineering, tissue engineering, biomedical engineering, creation
of counterfeit-resistant documents , nanolithography in microelectronics, optoelectronics, nanomachinesand many others. It is out of question that the
success of these novel applications lies on one crucial factor – the

Types of Impurities in single crystal semiconductor nanostructures

Hi,

I am looking for information about formation, distribution,
concentration and stability of impurties/ defect in semiconductors,
specifically for cubic SiC. I have some discrete set of
literartures which are neirther systematic, nor elaborate. I would truly
appricitate if any one can suggest me some references.

 

Sincerely,

Need help: Relation between polymer end-to-end distance and mechanical properties

Hi,

I found in polymer books and some literatures that mechanical properties of polymer improve with the increase of their radius of gyration or end-to-end distance for a fixed molecular weight. I, however, could not find any experimental evidence or any physical explanation. 

It will be a great help to me if anyone refer me some literatures that explains the connection between these two parameters.

 Thanks,

Ashfaq Adnan

Natural Frequencies for all elements in the Periodic table.

Hi, 

I am interested to know the natural frequencies of elements in the periodic table. I made some attempt to reveal this information but surprisingly ended with nothing. Perhaps I  did not search hard. Does anyone know about the natural frequencies of elements in periodic table.

 

Sincerely,

Why larger time step is not allowed in Molecular Dynamics Simulation?

Hi, 

I am trying to understand why MD simulation crashes if larger time step (~100 fs) is applied to integrate the equation of motion. I know that there are two major things play role in solving F = ma and obtaining equilibrium solution. One is the accuracy, and the other is numerical stability of the integration algorithm.
