Virtual Special Issue: CFD simulation of pedestrian-level wind conditions around buildings: past achievements and prospects
This Virtual Specail Issue deals with papers on CFD simulation of pedestrian-level wind conditions around buildings, published in the Journal of Wind Engineering and Industrial Aerodynamics (JWEIA).
Force and stroke of a hydrogel actuator
Hydrogels that undergo a volume phase transition in response to an
external stimulus are of great interest because of their possible use as
actuator materials. The performance of an actuator material is normally
characterized by its force–stroke curve, but little is known about the
force–stroke behavior of hydrogels. We use the theory of the ideal
elastomeric gel to predict the force–stroke curves of a
temperature-sensitive hydrogel and introduce an experimental method for
measuring the curve. The technique is applied to PNIPAm hydrogels with
low cross-link densities. The maximum force generated by the hydrogel
increases with increasing cross-link density, while the maximum stroke
True Stress-Strain curve of metals
Hi everyone!
I was hopping to find some help over here. I just need some references or links to the true stress-strain curves of differents metals. I'm working with Tin and i'm going to do run some compression test to valid an analitic method. In order to do this, I need the strain-hardening exponent (n) and the strength coefficient (C) and it's being impossible to find those.

Fracture analysis of crack using ANSYS
HI,
I trying to find the SIF for a crack on lower jaw of a locking piler. Please somebody tell me how to insert edge crack in 3D body.

Stabilization method in local instability problems
Dear all,
in commercial FE codes, such as ABAQUS, ANSYS, there is option to get convergence in quasi-static analysis by using artificial damping factor. I tried to dig their documentation about this method, but it is somewhat sparse. Could some body recommend me some literature about this topic so that I can gain a better understanding about it.
I thank you in advance.
Sincerely yours,
Ken
