Large deformation and instability in gels
I'm attaching slides of a talk that I gave yesterday at the Schlumberger-Doll Research Center. In preparing the talk, I made liberal use of slides prepared by Wei Hong for his own presentations. The talk is mainly based on the following papers:
Postdoctoral position at RPI in modeling respiratory motion during cancer radiation therapy
Brief description: There is an
opening for a postdoctoral research position in the Advanced Computational
Research Laboratory at RPI, Troy, NY to work on an ongoing R01 reesearch project sponsored by the National Institutes of Health on the modeling of respiratory motion from patient-specific 4D CT images. In external beam radiation treatment, a lethal radiation dose is delivered through precisely conformed

Cell tractions are the outcome of the complex process of cytoskeletal force generation that cell uses to maintain structural stability, to sense the physical environment and to propel itself. We are only now beginning to understand the process of cytoskeletal force generation, and we cannot yet say much about the losses in transmission through focal adhesion/integrin complexes (attachment ‘islands’ at the cell-substrate interface), but we can definitely measure the tractions that result from cytoskeletal force generation. The mechanics behind the measurement method might be of interest to the wider audience of iMechanica, as it involves an interesting inverse problem and different solution methods that have incited lively discussions in past years.
Seeking candidates for positions in Houston, also positions in Germany
Our agency, Reliability Analysis Associates, Inc., specializes in recruiting Reliability Engineers and related skills. For a client in the oil business in Houston, TX we are seeking candidates for two positions that require knowlege of finite element analysis, crack growth, reliability, and low cycle fatigue. The two job descriptions are attached.
Not just another pillar compression paper
We show that it is possible to distinguish between homogeneous and heterogeneous dislocation nucleation on the basis of differences in experimentally measured theoretical strengths. From nanoindentation tests, the critical shear stress for dislocation nucleation in two different Mo-alloy single crystals (Mo-3Nb and Mo-10Al-4Ni) is found to be ~1/8 of the shear modulus. The corresponding stress in uniaxially compressed Mo-10Al-4Ni micropillars is ~1/26 of the shear modulus.

Hi:
Position in R&D with Schlumberger
Schlumberger, in relation with its R&D effort related to Co2 Storage
(http://www.slb.com/carbonservices), is looking for a highly innovative
and motivated individual with a background in geo-mechanics to join its
multi-disciplinary engineering team. A PhD in a field related to
geo-mechanics (Solid mechanics, fracture mechanics, civil engineering,
geophysics etc.) is necessary. No prior work experience is required. The
candidate must have experience in numerical and analytical modeling:
Differences between cohesive/interface/embedded process zone
I am PhD student and i'm working on the behavior of bonded joints under impact and i have one question :What are the differences between a cohesive element, an interface element and a embedded process zone element ? Do they have fundamental differences or it's only a difference of the cohesive law expression.
