If I don't turn on the Nlgeom on, what will happen for a elastic material. I mean Abaqus will consider the local elasticity for a built-in-end of a elastic material cantilever beam or not. What will happen to displacement for that beam. The FEA result should be equal to delta= FL^3/3EI or larger...
ABAQUS was giving me an error that bad meshing and some elements are distorted. However, the job was completed successfully. I am just wandering the result I get is okay or not.
Any suggestion?
hi helppoorpeople!
Thanks for your reply. So for silicon what will be the value of damping factor . I am need to use that factor for Steps?
Please let me know.

My beam model worked fine for a small load. However, whenever I was trying to give a large load, its giving me an warning massege "2 negative eign values" and followed by an error message. I am sure the load is not too much for the model. Any one have any idea whats going on and how I can avoid...
Hi Xref.
For using the Amplitude option I think I have to put exaxt time value. However for my case I am not sure what time it will take to deflect fully. As I want to let the beam deflect fully and then let it appear at the unloading position.Do you have any idea how I can use time period...
Thanks all for the reply. The material is silicon, which is elastic. Usually silicon bulk material does not undergo any fatigue failure. However, recent studied shows that silicon microfilm undergoes fatigue failure under high stress cycles. So I am not sure Fatigue Calculator can do that or...
Dear All,
For silicon material is there any analytical approach from where I can calculate fatigue life from the stress (found from FEA). The applied fatigue load is for high cycle fatigue. I also collected some experimental data. Does anyone have any idea or suggestion?
Thanks
Roy.
