Dear all
I want to model 300000 cycles of loading with maximum and minimum value for force as a fatigue loading.I want to model this problem in abaqus and I have several idea for it but not sure about them.would you help me what to do?
many thanks
Structural topology optimization, which aims at placing available material within a prescribed design domain appropriately in order to achieve optimized structural performances, has received considerable research attention since the pioneering work of Bendsoe and Kikuchi. Many approaches have been proposed for structural topology optimization and it now has been extended to a wide range of physical disciplines such as acoustics, electromagnetics and optics.

Hi, all,
I was trying to run a Matlab m file to do some post precessing in my optimization loops. I need to run it as a batch mode without opening either Matlat interface or command window. I was trying multiple ways and it doesn't work. Any experience on this, PLEASE let me know!
So, my question simply as "I need to run obj.m and get design.txt". I've already used fopen and fprintf to write output txt file. I need to know how to run this obj.m file! Thanks.
Best Regards,
Aaron
Hello Abaqus members,
I am doing an explicit simulation of a simple fork and fiber system. The parts have a node to node connectivity. The fork is subjected to a sinusoidal load, and I am interested in the displacement at the tip of fiber.
Here are some movies of impact fracture of various test cases, recorded at up to 5Mfps using the new Kirana camera. The sensor is not the final one yet, but the results are promising. Wedge loaded PMMA plates with holes reveal very nice crack branching (somewhat analogous to fireworks). My students Y. Rotbaum and A. Godinger who performed to test cases thought that Haendel "lascia chio pianga" is appropriate. I don't take a stance on that!
Enjoy:
I have done flat plate tensile test experiment with plate having u notch at different angle to get mixed mode behaviour.The experiment shows the force variation F(30 DEG)>F(45 DEG)>F(0 DEG)>F(60 DEG) While fem elasto-plastic model made in abaqus shows F(0 DEG)>F(30 DEG)>F(45 DEG)>F(60 DEG).
Can anyone tell me why this contradiction is there between experiment and fem model.
The project addresses tissue modeling for the pharynx region and is a part of a larger project addressing the obstructive sleep apnea syndrome (mechanical, fsi, medical angles). See www.jobbnorge.no/ledige-stillinger/stilling/101325/phd-positions-in-sof… for further info. Deadline is 15 May.Expected start-up is summer 2014.
