Project Description:
The biology of the inversion process in Volvox carteri is examined, and a coupled mechanical and kinetic model is proposed. See attached proposal for details. The presentation given is also attached here, as well as the final paper. Also, a movie of the simulation that made all of the work wroth while, the inversion of a half-sphere, is attached here as well. Note: The file inversion2bw.doc is a movie, just download it and change the extension to .avi. This has to be done since iMechanica doesn't allow attachment of .avi files directly.
Dear every body,
I want to make experiment to find out cofficient of friction between two metal (steel), what is the ASTM code accord with that case?
Please help me

Joni Jon
Composite Vehicle Research Center (CVRC) at MSU has an immediate opening for a postdoctoral research associate to conduct research in non-destructive evaluation (NDE) and structural health monitoring (SHM) of composite materials in an effort to develop self-diagnostic composite structures for air and ground vehicles.

Hi,
I have cyclic uniaxial compression data of a PU. When I look at nominal stress vs nominal strain then the relation is clearly nonlinear (increasing stiffnes with increasing strain). When I convert to true stress vs true strain I still have a nonlinear relation, however, not as strong and the stiffness decreases with increasing strain.
When I look at true stress vs stretch, however, the relation seems to be almost (I'm only talking about the first loading cycle) linear. Nominal stress vs stretch is still nonlinear.
Hello!!I am a new user of ABAQUS. I have a question about obtaining of the frequency response function in ABAQUS. In the first step I calculate the natural frequency using the step linear perturbation(procedure type)/frequency.I think that obtaining the frecuency response function, I need to use in the second step the steady-state dinamic,modal.I don`t get to plot the amplitude of modal-frequency graphs.I would apreciate much if someone could help me about this question.
Many of you developed Finite Element codes. These codes are usually quite complex. So you all know the importance of testing your results to see if what you programmed makes sense. The usual approach is to compare your FEM program with somethig already published. With this in mind, I designed a series of "lectures" on the topic of elasticity solutions for plates. You can find the details in
I am modeling a RBC(red blood cell) membrane using shell181 element and
using neo hookean model. But when I try to solve it, it gives error. I
couldnt figure out the cause. Please help me.
This is my input file for creating the model.
