Dear colleagues,
Consider a simple non-linear elastic material with stress given as
σ = D(εdev) εdev + B εiso
where εdev is the norm of εdev, D is a function of εdev and B is constant. The material is isotropic since the principal directions of σ and ε will coincide.
Professor Wei Lu received the 2014 Gustus L. Larson Memorial Award. This award was presented to Dr. Lu by the president of ASME, jointly with the president of Pi Tau Sigma, during the 2014 ASME International Mechanical Engineering Congress & Exposition.
It is my pleasure to solicit nominations for the "Eshelby Mechanics Award for Young Faculty". This award, launched in 2012, is given annually to rapidly emerging junior faculty who exemplify the creative use and development of mechanics. The intent of the award is to promote the field of mechanics, especially among young researchers. While interdisciplinary work that bridges mechanics with physics, chemistry, biology and other disciplines is encouraged, the ideal awardee will demonstrate clear inspiration from mechanics in his/her research.
It is with great sadness that we post this entry. Ted Belytschko passed away early this morning, 15 September 2014.
When Working on Ansys Non Linear Static Structural Analysis, I couldn't comprehen while defining and assigning material properties to corrosponding bodies.
When I give different random values for density in Engineering Data and runing the jobs parallely the results look SIMILAR for all the independent values, I couldn't fish out on what basis do the software is giving out results.
I'm working on a Multibody dynamics code using the finite element method to simulate the behaviour of flexible beams (using this paper if anyone is interested/ it is relevant). I'd like to model joints, and as I only need spherical friction free joints I believe this should be easy using Lagrange multipliers.
When I run the code, the two bodies part company immediately. Any ideas where I'm going wrong? I'm just simulating a double pendulum with 10 elements in each body for now.
Professor James R. Rice, of Harvard University, will receive the 2014 Theodore von Karman Medal. Here is a link to an announcement.
Lallit Anand will receive the 2014 Drucker Medal. There will be a symposium in his honor at the International Mechanical Engineering Congress & Exposition, 14-20 November, Montreal, Canada. See you there.
