What are all the physical significance/meaning that can be obtained from a STIFFNESS MATRIX ?

Submitted by Anonymous (not verified) on
education

Hi everybody,

 Can any one explain what is the physical meaning that a stiffness matrix illustrate ? I am a learner at a starting level in this Finite Element Analysis field . There are some questions which I wish to get an idea upon ...

 1. What exactly Stiffness Matrix tells about the structure ? Can you please explain with an example like "Linear Timoshenko Beam or Bernoulli beam or like 4-node plane stress element"....

 2. What is the relation between the eigen values of a stiffness matrix and the corresponding rigid body modes ? 

1D Plasticity - Isotropic hardening, tutorial with examples.

For those who may be interested,

 I have put together a paper describing 1D plasticity for a variety of cases of isotropic hardening.  The material is not new, but hopefully it is written with enough detail that it will help beginners learn some basics of computational plasticity.  The notation and material closely follows "Computational Inelasticity" written by Simo and Hughes.

Looking for a PhD student

Submitted by pschiavone on
education

I'm looking for a PhD student to work in the area of solid mechanics, specifically applied mathematics in linear elasticity using complex variable methods and/or boundary integral equation methods.

I'm a professor in Department of Mechanical Engineering at the University of Alberta in Edmonton, Alberta, Canada (although I am an applied mathematician by training).

Attached is an intriguing commentary on the scientific method through an example, written by my good friend, Luc Tartar. The specific example is that of trying to understand what 'light' might be, especially from a mathematician's point of view. The mathematician in this case is an extremely talented one, who also happens to actually understand a whole lot of physics and mechanics.

Lego Man in Space

For an interesting news article about the mechanics behind Lego Man's balloon voyage to space, read the Toronto Star article by Mary Ormsby. She writes, "A 1,200-gram weather balloon, the crucial role of gravity, quiver-reducing ropes, Styrofoam’s versatility, burst altitude, a University of Wyoming website and a free software program for shutterbugs were part of the formula Mathew Ho and Asad Muhammad, both 17, used to launch, film and land the patriotic, flag-bearing Lego Man..."

Hyperelastic material characterization: why they call it the pure shear specimen

pure shear

Many people puzzle over the nomenclature of the pure shear test. They rightly point out that 1) the Pure Shear test piece is loaded in tension by extending the specimen in the axial direction, and 2) a shearing deformation, by definition, involves the lateral motion of parallel planes. They wonder where is the "shear"? and what does it mean to say that the shear is "pure"?  Here, we review the origins of the terminology.
