A postdoctoral associate position at MIT is available immediately, focused on the analysis and development of bioinspired, adaptive thermal management structures, by using theoretical and atomistic multi-scale modeling and simulation.

My research topic is too different from string theory!. but i think this not so old opinion of Proff. Lee Smolin about world research system weaknesses is very beneficial to read. and have convincing arguments in neccessity of changes in this system. Read this. it is not related to string theory,

Hi everyone,

I am trying to build polycrystal plasticity model  by using UMAT subroutine in ABAQUS. As we know, the orientation of grain is always espressed by Euler's angles. What I want to know is  how to assign different initial orientations to different grains using Euler's angles in Umat subroutine. Could anybody tell me how to do? Is there any example ?

Many Thanks,

Yuanpei

Rob Wood teaches a course on micro/nano robotics, and asks me to give a 30-minute tutorial on the theory of dielectric elastomer actuators (DEAs).  I attach my slides, which might be useful to you if you'd like to include this topic in your class.  The tutorial draws upon work in the literature, as well as recent work in my group:

(This message was sent to iMechanica by Ken Chong, of the National Science Foundation).  This letter is to call your attention to an opportunity to broaden participation particularly of underrepresented students in Ph.D. programs in engineering through supplements to current research grants funded by the divisions in the Directorate for Engineering (ENG) at the National Science Foundation.

The main idea is the following: a most natural mathematical setup for considering the motion of the void-solid interface of an expanding void is that of the traveling wave. Thus, a theory for macroscopic damage evolution may be suspected as being a homogenized version of basic theory that has such wave phenomena as an essential ingredient. This paper is a first step in probing such questions. 

Early this week the number of registered users passed 6000.  Our growth rate remains nearly a constant, about 10 new users per day. In January Teng plotted some basic statistics of iMechanica.

I am designing a new course on FEM, to be offered privately in India. It will emphasize fundamentals, and try to supply (or bring out) the physical interpretations behind the mathematical formalisms.

Well-known for its high yield strength, metallic glass often suffers from its low ductility and intrinsic brittleness, as discussed in a recent iMech jClub theme on plasticity and failure in metallic glasses led by Yanfei Gao.

We present a coupled mathematical model of growth and failure of the abdominal aortic aneurysm (AAA). The failure portion of the model is based on the constitutive theory of softening hyperelasticity where the classical hyperelastic law is enhanced with a new constant indicating the maximum energy that an infinitesimal material volume can accumulate without failure. The new constant controls material failure and it can be interpreted as the average energy of molecular bonds from the microstructural standpoint.

In MEMS fields, a need arises in engineering practice to predict accurately the nonlinear response of slender post-buckling beams, especially the nonlinear transverse stiffness. The bistability of the post-buckling beams is excellent in reducing power consumption of micro-devices or micro-systems. However, the major difficulty in analyzing the post-buckling and snap-through response is the intractability of the geometric nonlinear control equations of large deflection beams.

The Materials Research Department at Risø National Laboratory for Sustainable Energy, Technical University of Denmark, is seeking a PhD student within the field of advanced fibre composites. The PhD position will aim at increasing the fundamental knowledge of wood fibres and their behaviour as reinforcements in composite materials studying e.g. wood fibre structure and mechanical and hygroscopic properties e.g. by micromechanical modelling and advanced testing.
