Dear Colleague,

The 21st Australasian Conference on the Mechanics of Structures and Materials (ACMSM21) will be held at the Conference Centre of the City Campus, Victoria University, Melbourne, 7-10 December 2010. The conference will be hosted by the Faculty of Health, Engineering and Science, Victoria University, Melbourne, Victoria, Australia.

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).

Please pass the information to anybody who may be interested.

Dear all

 I am doing my dissertation on laser forming of 304 stainless steel. as part of my dissertation I need to model the proces by Ansys. I need the to know how the properties such as density, thermal expansion etc change with temperature.

does anyone knows from where I can found such information please?

Thanks for your help

The Global Enterprise for Micro Mechanics and Molecular Medicine (GEM4, www.gem4.org) and the Research Centre of Excellence (RCE) in Mechanobiology will be organizing a Summer School on Cellular and Molecular Mechanics with a focus on Mechanobiology. The 2010 GEM4 Summer School will be held from July 25 - 31, 2010 at the National University of Singapore. This 2010 Summer School will comprise both lectures and lab demonstrations.

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.

ScienceWatch.com (affiliated with Thomson-Reuters), has ranked University of Illinois as the most cited institution in engineering from 1999 to 2009 (http://sciencewatch.com/inter/ins/10/10febTOP20ENG/).  It is followed by Berkeley, MIT, Stanford, University of Michigan, and Georgia Tech.
 
For each institution, ScienceWatch.com has also listed a few research directions that have received most citations.  The mechanics work by Professors Yonggang Huang (University of Illinois), Huajian Gao (Brown University), Bill Nix (Stanford) and Hutchinson (Harvard) on Mechanism-based strain (gradient) plasticity leads the list from the University of Illinois.

A fully funded PhD position is available in the area of multi-scale modeling of geomaterials within the research project Failure of cohesive geomaterials: bridging the scales - GEOBRIDGE at Laboratoire Sols, Solides, Structures – Risques (3S-R), Université Joseph Fourier, Grenoble, France.

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 ^^

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.

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 

I finished the grad course on Mechanics of Soft Materials. It took 14 weeks with 2 academic hours per week and it covered the following topics: 1 Tensors 2 Kinematics 3 Balance laws 4 Isotropic elasticity 5 Anisotropic elasticity 6 Viscoelasticity 7 Chemo-mechanical coupling 8 Electro-mechanical coupling.

I attach the class notes and I will be grateful for the remarks, corrections, and criticism from iMechanicians.

I am pursuing my Ph.D.in Soft Contact Manipulation. I want to understand Hertz Contact Model very clearly.Can any one help me to understand it or Give me some helping material. It is very difficult to understand it from Contact Mechanics (K.L. Johnson).

Dear Colleagues,

IOSO optimization technology has been used in turbomachinery for more than 20 years and applied on real-life objects like aircraft and power engines. Let me offer you some more examples.

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.

Following Griffith, you perform the same fracture test using a steel rather than a glass. Using a diamond saw, you cut a crack into a body of a steel. You load the body in tension, and record the applied stress at fracture. You find that the Griffith theory agrees with one part of the experimental observation, but disagrees with the other. While other people complained about this large discrepancy, Irwin and Orowan did something about it: they invented a procedure to apply the Griffith theory to ductile materials such as steels.
