I have an assembly with a large number of parts with contacts. I am solving for a pressure load. I get a max to min coeff. ratio that is very large. My model never converges. I suspect it is due to rigid body motion. I have carried out a modal analysis of the assembly and sub-assemblies and no...
I am a PE in Ohio. I am trying to find out what I need to do to be certified in California. Any help will be appreciated.

Time is an illusion. Now is the only thing there is.
Hello,
I recently lost my job and would like to start doing FEA consulting. I would like to start with an inexpensive FEA software. I am thinking of linear, some linear (material) and dynamic analysis. Could some body suggest a commercial softwre? I have used ANSYS and ABAQUS in past.

Gentlemen and Ladies,
I am working with a Ductile Iron material (65-45-12): uts-65000 psi, yield pt-45000 psi, elongation-12%. I have a part made from this material, which has a bore and a hole prependicular to the bore. Hole dia is about 1/4 inch and bore diamter is 5 inch. I have carried out...
All FEA Experts,
I am thinking of starting a FEA consulting business. It will be a one man show in the beginning. I have experience in Linear/Nonlinear, Static/some Dynamic analysis. I would like those in this business to please provide some tips from their expereince.

I am considering buying a workstation with with two quad core processors. I use ABAQUS software. Will it be equal to buying 8 single processors. Pleas give me your comments.
Thanks,
Gurmeet

I have been running ABAQUS on a workstation. Operating system is SUSE Linux 9.3. The workstation is a dual processor AMD Opteron machine with 8GB memeory. I have been using ABAQUS on this machine for a couple of years without any problem. However recently my ABAQUS jobs have been ending due to...

I have an application for fatigue evaluation where the stress goes above yield. I have briefly surveyed the literature both FEA and fatigue. It appears that I need to specify cyclic stress-strain properties. The materials are AISI 4140 (UTS 150000 psi) and steel UTS 80000 psi. If any one could...

What accuracy can be expected from FEA stress results as compared to experimental test results? Recently I have heard from experts that agreement within 10% is achievable for both linear and non linear analysis.
In machine parts high stresses usually occur in areas of stress concentrations...
I work for a compressor manufacturing company. Currently we use ASME Section VIII to design compressor cylinders. By designing I mean figuring out thickness of walls and deciding reinforcement around holes. Strictly speaking code is not applicable to compressor cylinders. However we have used it...

Greetings to everybody,
I use ANSYS software for FEA. I have a question regarding interpretation of results. If I plot the results of the analysis (equivalent stress SEQV)of the compressor cylinder head mentioned in my last post, the maximum stress value SMX is 123000 psi. This run was made at...
