A challenge to Mr. Koenemann

Submitted by Chad Landis on

I am sure that several of you have followed Mr. Koenemann's posts with some interests.  For some it might be entertainment, and for others it might be like watching a car wreck.  In any case, several iMechanicians have attempted to convince Falk that his theories do not make sense.  We have all failed miserably at that task.  I am perhaps a bit slower than most, but it is clear to me that Mr. Koenemann will not be convinced by any physical or mathematical arguments.

Beam analysis

Submitted by Anonymous (not verified) on

hi all,

 I am trying do analysis on a beam in ABAQUS which is coated with polymer meaterial and i have to test it in following conditions,

1. Humidity resistance: 50 ° C/85 ± 4% RH for 8 days

2.  Warm salt water: 58 ± 2° C/5% salt-water immersion for 8 days

can anyone tell me how to do this one...

Buckling of Stepped column

Submitted by GOPALAERO2000 on

Hi everyone,

Does anyone have the work experience on stepped column kind of structure?

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

Coupled Eulerian Lagrangian Analysis

Submitted by kunal_mecadcam on

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...

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

Cell sensitivity to substrate stiffness

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

Submitted by llguang on

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.
