Erdemir Laboratory at the Cleveland Clinic (http://www.lerner.ccf.org/bme/erdemir/lab/) has three positions for an upcoming project on the biomechanics of multi-layer tissue structures of musculoskeletal extremities with emphasis on computational modeling & simulation. The positions will initially be for a duration of one year with the possible extension to three years.
I'm facing problem while writing a script for a parametric study.
After changing the each parameter the model changes and and the loaction of the interested element changes based on those parameters.
Also the element number changes.
Is there any command in python script to choose the elements based on the location ?
I am Kun Luan, a doctoral graduate from China. I am now looking for a postdoc position in damage tolerance, failure analysis, and fracture mechanics for composite materials, and advanced numerical methods for structural analysis. I already got my PhD degree of engineering in March 26,2014.
I have a one dimensional bar with a triangular pulse given at one end for 2 microseconds. The boundary conditions are free-free.I am having two cases. One in which the deformation is local (Hooke's law) and other in which the deformation is dependent on a kernel of radius r (say 5* element length).I find that the wave speed is higher when the deformation is non-local as compared to local deformation case. Is this correct? Is there a way to verify the solution?
It is a long-standing goal in metallurgy to enhance the strength of materials without sacrificing ductility. In a recent article in Nature Communications, we reported an effective way to evade the strength-ductility trade-off dilemma in twin-induced plasticity steel.
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!
New research is emerging out of a project where Ohio State University used our software to reconstruct the anatomy of an ant neck. In this project, micro-CT scans of an ant neck were reconstructed using Simpleware software and exported as a mesh for analysis in Abaqus.
The engineering analysis group at Baxter Healthcare has an immediate opening for an FEA analyst at the Senior Principal Engineer level. The person will work from the Baxter R&D facility in Suzhou, China, and report to the manager of analysis group in Round Lake, IL.
Applications are invited for few open positions in the area of
multiscale simulation of fatigue and fracture of advanced alloys and
nano-material based composites. Primary focus of this research is investigation
of fatigue and fracture behavior of nanomaterials and to develope various
constitutive models for continuum, based on large scale atomistic simulations.
Research effort will include development of analysis and design methods toward
improving material/structural behaviour using computer simulation. Interested
candidates should have preferably MTech/ME degree in
mechanical/civil/aerospace/material engineering discipline with good knowledge
We simulate the fracture processes of ferroelectric polycrystals in
three dimensions using a phase-field model. In this model, the grain
boundaries, cracks and ferroelectric domain walls are represented in a
diffuse way by three phase-fields. We thereby avoid the difficulty of
tracking the interfaces in three dimensions. The resulting model can
capture complex interactions between the crack and the polycrystalline
and ferroelectric domain microstructures. The simulation results show
the effect of the microstructures on the fracture response of the
material. Crack deflection, crack bridging, crack branching and
ferroelastic domain switching are observed to act as the main fracture
toughening mechanisms in ferroelectric polycrystals. Our fully 3-D

full-thickness cartilage lesions of the knee caused by trauma, disease or joint
instability are a common disorder affecting people of all ages. Implanted
cartilage replacements (ICR) have the potential to overcome the limitations of
conventional treatment methods and are a promising approach to restore
functionality of the joint. In spite of some success in engineering
