help about secnd order effect in columns

Submitted by hany_333 on

ello all,

I am an M.S student, my subject in modelling of high strength concrete column under eecentric loading. I made a model of reinforced

 concrete column with in ANSYS by solid65 to represent concrete and link8 for steel.

My model is 200*200*4000 mm, i choose multi., conc.,and elastic linear for concrete, closing crushing for it, for steel bilinear, elastic.

Slenderness ratio (l/d)=20 Although Using large displacement analysis option, model give me very small displacement (less than

Material properties and temperature

Submitted by ghayth81 on

Hi All,



 As you know the material properties such as Modulus of Elasticity, Poisson's ratio and Shear Modulus are temperature dependent. Especially, the polymer material as it shows significant reduction in strength and stiffness with temperature increasing.



I did a tensile test on adhesive material at different temperatures. The results showed that the E-modulus is reduced about 70% at 60 °C and the Poisson’s ratio increased also.

Capturing wetting angles in transient simulations of fluids

Submitted by Mikael Öhman on

Dear all,
I'm trying to simulate the transient behavior of a fluid and I'm finding it very difficult to capture the wetting angle.
To begin with, I only considering the idealized case.

The common approach is to apply the pressure load
p = 2 H γ
where p is the pressure (normal traction) on the surface, H is the Gaussian curvature of the surface, and γ is the surface energy
This load will of course always yield the same equilibrium shape for a viscous fluid, regardless of the value of γ.

Now, comparing with Young's relation, where one obtains a balance containing surface energies for every interface.
