I would like to know, how to determine the crippling load for stepped column kind of structures? If anyone have the materials pertaining to the subject, please do share (if interested).

Thanks and Regards

Fluid Structure Interaction

Hi every one,

I am in my final stage of my dissertation, which is about slamming analysis of boat hulls with help of CEL - in Abaqus. I am currently working in how to validate the results which I got. Is there any way except experimental method to validate the stress - strain results?

Please help me...

Wind Tunnel Experiment

In our wind tunnel experiments, we have wake survey of a cylinder and boundary layer measurement for a thin flat plate as two experiments. We measure the stagnation pressure(Pt) at points using a pitot tube. We also measure the static pressure of the free stream Pinf.

Cell sensitivity to substrate stiffness

Submitted by Daniel Isabey on Wed, 2009-04-15 15:03.

In Féréol et al. (Biophys. J., 2009, 96: 2009-2022),

we propose a coupled theoretical and experimental study in order to understand the

mechanism of cell sensitivity to substrate stiffness. To do so, we first consider

that adhesion sites pass through different stages of development, e.g., Initial

Adhesion (IA), Focal Complex (FC), Focal Adhesions (FA), characterized by the

dynamic crack initiation

Hello everyone, I am studying the dynamic crack initiation problem of composite material. Just like the below imagine ,a crack perpendicular to the interface of two different materials, under dynamic load, the crack will propagate, at the crack tip I use the singular element to simulate the stress and strain state. after I have the crack tip stress, how can I calculate the energy release rate of different direction, for example, also along the original crack line or perpendicular to the original crack line., or kink from the 45 degree of original crack line.
