A quasi-static atomistic simulation method at finite temperature

Molecular dynamics (MD) method is an important simulation tool, but its results are always doubtful due to its unrealistic high strain rates. In this paper, a hybrid quasi-static atomistic simulation method at finite temperature is developed, which combines the advantages of MD for thermal equilibrium and atomicscale finite element method (AFEM) for efficient equilibration. Some temperature effects are embedded in static AFEM simulation by applying the virtual and equivalent thermal disturbance forces extracted from MD. Alternatively performing MD and AFEM can quickly obtain a series of thermodynamic equilibrium configurations such that a quasistatic process is modeled.

Journal Club Theme of March 2014: 3D Experimental Measurements in Soft Materials

3D Experimental Measurements in Soft Materials - from measuring cell displacement fields to complex hierarchical material deformations and beyond

The Why? - Why do we need 3D material deformation measurement?

This is an excellent question. If material surface deformation field descriptions are of prime interested, then Digital Image Correlation and interferometry techniques provide the user with a mature field available experimental approaches that might fit the bill [1]. However, if the material of interest presents itself with an internally non-homogenous, non-periodic or simply 3D microstructure, 3D internal deformation measurement techniques might be the only way to investigate the material’s deformation, and ultimately its constitutive behavior.

Publication citation metrics and h-index for Australian Universities


For similar reasons outlined by Zhigang’s post http://imechanica.org/node/2345 I
have found it necessary to find comparisons in publication citation
metrics/indices whilst in Academic employment. Much has been discussed about
the appropriate use of these metrics and the arguments on the benefits and
drawbacks are both compelling. Whatever your opinion, it seems that for the
foreseeable future these publication citation metrics are here to stay.

MODELLING OF ADVANCED MATERIALS FOR SIMULATION OF TRANSFORMATIVE MANUFACTURING PROCESSES 

 

The project will form one of the integral parts of a collaborative UK/India research grant, which is funded by the EPSRC and the Department of Science and Technology, Government of India.

Duration: 1 year

Deadline for application: 25 March 2014  

 

The projects aims to:

 


Comparing experimental fracture properties and micromechanical (or global-local/multiscale) finite element simulations

I am interested in developing a global-local finite element model (micro/macro) to simulate flexural testing of a composite material. Flexural loading will be applied on global model (macro) and crack propagation will be simulated in the local model (micro). I want to compare stress intensity factor or any other fracture property obtained from local model (micro) with that of experimental results.

I would appreciate if anyone could suggest some references/literature in this area. Any kind of suggestions would be great!

Microplane modeling of shape memory alloy tubes under tension, torsion, and proportional tension–torsion loading

In this paper, a phenomenological constitutive
model based on microplane model is used to simulate tension, torsion and proportional tension-torsion on NiTi thin-walled tube. Validation of the
microplane model against experimental results in different loading conditions demonstrates
the capability of this approach.
This publication will benefit the numerical and experimental study on SMAs.
