Crack propagation in brittle materials with anisotropic surface energy is important in applications involving single crystals, extruded polymers, or geological and organic materials. Furthermore, when this anisotropy is strong, the phenomenology of crack propagation becomes very rich, with forbidden crack propagation directions or complex sawtooth crack patterns. This problem interrogates fundamental issues in fracture mechanics, including the principles behind the selection of crack direction. Here, we propose a variational
Please join us for a national workshop on Microfluidics and Nanofluidics near Delhi, India during 14-16 July 2014. We are happy to have some higly accomplished academician in multiscale CFD domain. Prof. Suman Chakraborty, Bhatnagar Awardee 2013 will be principal instructor and speaker in the event.
We are preparing everything necessary to host the 3rdInternational Conference on Material and Component Performance under Variable Amplitude Loading (VAL 2015) in Prague, Czech Republic in March 23-26, 2015. From now on, you can register your abstracts in the online
submission system. The system will stay open till July 7, 2014, so do not forget to insert your abstract in time.
I am new to imechanica so pls forgive me if I make a mistake.
I have a coplue of doubts while recovering stresses from XFEM.
My problem statement has an inclusion with some eigen strain, embedded in an infinite matrix. I have solved the problem for displacements using XFEM. I need to get the stresses at a point close to the interface.
update, 7/24/2014: The information packet ("SFC2-challenge-v5.ppt") is no longer attached to this post (iMechanica has a file size limit of 1 MB, so we can not attach the 6 MB file). IF YOU WOULD LIKE THE INFO PACKET, PLEASE E-MAIL ME, firstname.lastname@example.org and copy Dr. Sharlotte Kramer, email@example.com. If you have an older version of the information packet, please also e-mail for the newest (v5) info packet.
We intend to send the shear calibration data to all those whose e-mail address I have by August 1st (sorry for the delay!).
You are cordially invited to submit an abstract to Symposium XX: Bridging Scales in Heterogeneous Materials at the 2014 MRS Fall Meeting & Exhibit, to be held
November 30 - December 5, 2014, in Boston, Massachusetts.
Phani Motamarri, from the University of Michigan, is the 2014 Melosh Medalist for his paper "A Spectral Finite-Element Based Method For Large-Scale Quantum Mechanical Calculations Using Kohn-Sham Density Functional Theory". Please join me in congratulating Phani!
