The Universitat Politècnica de Catalunya (UPC, http://www.upc.edu/eng ) opens tenure-track assistant professor positions in Computational Mechanics. Please follow this link for more information.

A post-doc position is offered at the Ecole Centrale of Nantes France.

hi all,

my name is christian, i'm a master degree student in mechanical engineering. i've been doing a swaging  process simulation using MSC.MARC, but i have a problem.when i ran the simulation, there were some node or element that penetrated into the other element and/or rigid body. i tried to change the value of contact tolerance and mesh, but i got the same result (pentrated still happened). what should i do to solve this problem?should i use mesh adaptivity? please help me ^^

These notes were prepared when I taught fracture mechanics in 2010, and were updated when I taught the course again in 2014.

Notes on other parts of the course are also online.

The Microelectronics Research Center at the University of Texas at Austin has an immediate opening for a Post Doctoral Researcher in the area of nanostructured solar cells. It is desirable that an applicant have experience and interest in topics related to basics of solar cell design, fabrication and testing. Applicants from related areas such as optoelectronics or nanoelectronics will also be considered provided they have experience in device design, fabrication and testing. A successful candidate must hold a doctorate degree in Engineering, Applied Physics or other related areas.

The Microelectronics Research Center at the University of Texas at Austin has an immediate opening for a Post Doctoral Researcher in the area of large area nanofabrication of quantum dots. It is desirable that an applicant have experience and interest in topics related to nanolithography, reactive ion etching of deep nanostructures, and nano-scale material characterization. A successful candidate must hold a doctorate degree in Engineering, Applied Physics or related fields.

there are two analytical concepts that are very important in fatigue failure.the first one is crack closure and the others is residual stress .the first one is in behind of crack and the other emphasis in the front of crack tip. the question is if we use some devices such as AFM/SEM is it possible we model the energy filed during fatigue process?   if this idea can be investigated the second question can be asked: is there any similarity to model for different loading conditions? 

I appreciate if you also put your comment in my idea?

I finished the grad course on Mechanics of Soft Materials. It took 14 weeks with 2 academic hours per week and it covered the following topics: 1 Tensors 2 Kinematics 3 Balance laws 4 Isotropic elasticity 5 Anisotropic elasticity 6 Viscoelasticity 7 Chemo-mechanical coupling 8 Electro-mechanical coupling.

I attach the class notes and I will be grateful for the remarks, corrections, and criticism from iMechanicians.
