There are many reasons which cause these failures.
Failure within 6 months (50000) of running is not acceptable.
One of the reason for the failure might be overloading of the vehicle.
Punching of the vent holes creates Stress concentration in this region. So a better vent hole shape which brings...
To be specific
We do fe analysis of a wheel hubs for the forces arising due to the cornering effect. A part of the wheel hub is formed. From the stress values obtained in this analysis we calculate the fatigue factor of safety. Now I want to use the residual stresses arising during forming...
Hi friends,
Could anyone let me know as to how one can use residual stresses in FEA (ABAQUS). It would be very helpful if anyone can direct me to any information on this matter.
Thanks
It is very difficult to give a specific answer to your problem without knowing the errors and warnings specified in the message file.
However here are a few thjings which may help you in solving the convergence problem.
Convergence will be a problem in contact analysis when the BC is not been...
Thanks Brad,
Even though I have a resonably finer mesh in my model
I feel there should not be any hourglass problem.
I think I should run my model using Incompatible modes and check the same.
Thanks Brad for your answer.
I have another question relating to the same.
I am solving a shaft model with 5 pairs of contacts.The mesh(solid brick elements)is good. When I solve this model using Reduced Integration I observe that some energy is lost to control spurious energy modes. If the...
I want to use the Nonlinear springs to simulate as a compression only spring in Ideas.
i.e. there should be no displacement during tension (in the same way as we can use in Abaqus)
Topic on Nonlinear springs in the help menu of Ideas says : " the software assumes the spring characteristics...
