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).

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.

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 ^^

Applications of Fracture Mechanics
Submitted by Zhigang Suo on Fri, 2010-02-05 02:19.The qualitative picture of the fracture of a body may be well-understood, across disparate scales of length and time, from the distortion of electron clouds, to the jiggling of atoms, to the motion of dislocations, to the extension of the crack, to the drop of the load-carrying capacity of the body. This statement by itself, however, is of limited value: it offers little help to the engineer trying to prevent fracture of a structure. Hypes of multiscale computation aside, no reliable method exists today to predict fracture by computation alone.

New idea in fatigue problems
Submitted by uni_students2009 on Thu, 2010-02-04 13:18.there are two analytical concepts that are very important in fatigue failure.the first one is crack closure and the others is residual stress .the first one is in behind of crack and the other emphasis in the front of crack tip. the question is if we use some devices such as AFM/SEM is it possible we model the energy filed during fatigue process? if this idea can be investigated the second question can be asked: is there any similarity to model for different loading conditions?
I appreciate if you also put your comment in my idea?
Bes Regards,
Hadi

Nonequilibrium Thermodynamics in Solid Mechanics
Submitted by Eran Bouchbinder on Wed, 2010-02-03 12:44.Solids that are driven beyond their elastic limit exhibit strongly disspative and irreversible dynamical behaviors. Such behaviors call for the development of nonequilibrium approaches that go beyond standard equilibrium thermodynamics. In a recent work we have developed an internal-variable, effective-temperature non-equilibrium thermodynamics for glass-forming and polycrystalline materials driven away from thermodynamic equilibrium by external forces [1, 2]. The basic idea is that the slow configurational (structural) degrees of freedom of such materials are weakly coupled to the fast kinetic-vibrational degrees of freedom and therefore these two subsystems can be described by different temperatures during deformation. The configurational subsystem is defined by the mechanically stable positions of the constituent atoms, i.e. the "inherent structures", and is characterized by an effective temperature. The kinetic-vibrational subsystem is defined by the momenta and the displacements of the atoms at small distances away from their stable positions, and is characterized by the bath temperature.
