Journal Club February 2010: Mechanics of Patterned and Structured Interfaces
Submitted by Kevin T Turner on Sat, 2010-01-30 02:48.Welcome to February 2010 Journal Club! This month, I look forward to a lively discussion on the mechanics of structured and patterned interfaces in which geometry is used to tailor adhesion. Much of the work in this area has been inspired by a variety of animals and insects that have feet covered with small structures (often hierarchical and sub-micrometer in size at the end) that allow them to strongly adhere to a broad range of surfaces. The best known example is the Tokay Gecko (Gekko gecko), which can achieve an adhesion force much greater than its body weight and can quickly form and separate adhesive contacts between their feet and a range of smooth and rough surfaces. In the journal club this month I do not want to delve into the mechanics of Gecko a

Lectureship in Applied Mathematics at the University of Oxford
Submitted by goriely on Tue, 2010-02-09 07:53.Dear Colleague,
I am writing to advertise an opening of a lectureship in the Mathematical Institute at the University of Oxford
The lectureship is in the Oxford Centre for Collaborative Applied Mathematics part of the Mathematical Institute . I am particularly interested in candidates at the interface between mathematics and mechanics.
(Note that a lectureship at Oxford is a permanent Faculty appointment more or less equivalent to an assistant, or associate level in the US).
http://www.maths.ox.ac.uk/node/11296
Please pass the information to anybody who may be interested.

On efficient finite element assembly in Matlab
Submitted by Alejandro A. Ortiz on Mon, 2010-02-08 20:31.As we all know, finite element matrices are sparse and many memory can be saved if their sparsity is exploited. Due to the latter, we are often provoked to declare the nxn stiffness matrix as a sparse one just before the element loop. Be careful of this method since the larger the matrix the slower the assembly operations. There is a better and more efficient way to code the assembly procedure in Matlab. I will show how to accomplish this.

how to active adaptive mesh option in ADINA System?
Submitted by mostafahasani on Mon, 2010-02-08 14:19.hello to every body ;)
Iam hasani- gradute student
I'm new user in adina. i worked by ansys and abaqus for several projects.
in adina when i choose control>solution process...>adaptive meshing> full the program return it to none!.
i tried to understand about the reason. but in fact i can not find the problem.
i think in program , there are some constraints that should be change before the full adaptive meshing.
please help to find the problem. thanks

Load-displacement curve in ABAQUS
Submitted by afarin on Mon, 2010-02-08 08:18.Hi all
I want to derive a load-displacement curve for a compoaite laminate shell which is subjected to a uniform displacement field in ABAQUS. The problem is somehow similar to example 1.1.14.
I have derived the data for Reaction force of each node and also for the Us. The curve for the maximum node is plotted but the data are half of the values reported in Example 1.1.14. I don't know what's wrong with it. Please help me with this problem.

contact problem
Submitted by fluttermech on Fri, 2010-02-05 06:58.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 ^^
