Does there exist a negative dimensionless quantity?

Submitted by Guanchu Cheng on Wed, 01/23/2013 - 18:32

att.

I am just wondering if there exists a negative dimensionless quantity? It seems that all dimensionless numbers I encount in my field (fluid dynamics) are positive. what if it is negative? and if negative, what does that mean? I sense that:

the imposed negative sign for a dimensionless number is just an alternative expression for a special external boundary condition, rather than no longer a characteristics over an essential in a physical law that required for being independent of external boundary conditions.

The Laboratory for Soil Mechanics (LMS) of the Swiss Federal Institute of Technology in Lausanne (EPFL) is looking for a Postdoctoral research fellow working on design and predictive modeling of real scale experiments for nuclear waste disposal. The foreseen activities include the implementation of advanced constitutive models developed at the LMS in a FE code and the implementation of 3D FE computations to simulate the repository behaviour.

Dear Colleague

I am modelling a 2D three point bending to analysis the crack propagation , i have a question in the part of damage evaluation, does anybody know what is different between, B.K , power law and mod.independent? means when we select one of them. Thanks

Gear Simulation

I am doing spur gear contact simulation on abaqus when I do this driver gear rotate but driven gear not rotate as I observed in results.

So is there mistake in interaction module or constraint or boundary conditions?

I also followed instructions which were given to member " zeke2282".

Crack propagation with Gurson model

Submitted by Mohamed H.Miloud on Mon, 01/21/2013 - 12:49

research

hello

I identified a set of parameters of the Gurson model. How to use these parameters to simulate the propagation of a crack in a CT specimen?. In another way how to simulate the propagation of a crack with the GTN model?

thanks!

Plrase help me for this case

HI..

i am doing FEM analysis of composite plate[0/+45/-45/90]S in ANSYS. I just wanna now which material properties i have to give as input, lamina properties or laminate plate properties..??

waiting 4 an early response..
