The US National Academy of Engineering has published a list of Grand Challenges for Engineering. Ths US National Committee on Theoretical and Applied Mechanics is interested in developing a discussion on the implications of these Grand Challenges to the Mechanics community.
The US National Committee on Theoretical and Applied Mechanics is seeking proposals from US institutions interested in hosting the 2014 US National Congress on Theoretical and Applied Mechanics. If you are interested, please contact K. Ravi-Chandar: kravi [at] mail.utexas.edu (kravi[at]mail[dot]utexas[dot]edu) for more information.
PhD Position: Solid Mechanics/Biomechanics at KTH-Stockholm
A four to five-year PhD position focusing on the analysis of multi-scale phenomena in diseased blood vessels including atherosclerotic plaques has recently been opened at KTH Solid Mechanics. The position is fully supported by the Swedish Research Council.
I am a last year Ph.D student at University of Toronto. During my study, I developed MEMS force sensor-based micro-scale compression testing for micrometer-sized spherical biomaterials. I applied this system for mechanical properties characterization of polymeric hydrogel microsphere for drug delivery.
I am working on crack propagation . I am trying to figure what factors should be taken into account when the crack is being propagated using XFEM.
I am especially interested to know what happens to the additional dof's corresponding to enriched nodes. Once the crack is propagated and crack tip is at new location , we add new dof's corresponding to enrichment functions , but what happens to the information stored by the dof's of previous enriched nodes,do we forget them altotgether , or do we map it to the new enriched nodes?
Help! imechanica!
This might not be a smart question to ask, but if any of you can help me, it'd be great.
I have a DCB (sandwitch specimen) with a cohesive element in the middle. Studying pure Mode I case, displacement is applied at the end of the DCB. Cohesive element works great (it fails when one reaches max separations). But I am having a difficulity in extracting crack length (i.e. length of failed cohesive element) vs time step. I looked for Damage and Status commend, but it's not promising. (I'm pretty new to ABAQUS....)
I am doing my Masters Thesis on Application of Mesh free method on Laser cutting.
I am using Radial point interpolation method for evaluation of the shape functions.I have successfully applied it to the interior nodes and I am using weak form for the nodes on the natural boundaries.
I am facing difficulty in application of numerical integration for the functions in the weak form .I am using circular subdomain and applying Gauss quadrature formula for the numerical integration.
I would be glad if I can get some help in this regard.
Thank you
World Scientific Pub. Co. will soon (2008 Winter) publish a new graduate textbook on Micromechanics and Nanomechanics. The book is based on a lecture notes that have been used in Berkeley for seven years. Reading of book requires minimum knowledge of continuum mechanics and mathematics, and the book is intended for the first year graduate students as well as those practitioners who have no time to read the literature for self-study.
