Re: Need help regarding 3 point constraint system
The animation will look slightly different if you change the point location, because you are changing the resultant (that is approximate it to 0, but not 0). This of course will affect displacements...

Interesting. Another point that I somehow didn't yet see is that there will of course be a stress concentration around the hole, so the evenly distributed pressure on A2 is an incorrect approximation...

Hmm... this is probably stretching the capabilities of Mechanica a bit! If you assume that your component only deforms elastically (no yielding or fracture), then perhaps you could set up a contact...

So, with this Total Strain Energy measure is equal to your calculated m×g×h. You are saying that at the critical point, the mgh energy is converted into the Total Strain Energy? Based on this, defining...
View ArticleRe: Use a measure to calculate force in simulate
If nothing yields and the deformation is purely elastic (both component and floor) then yes, I believe that all the energy should be converted from kinetic to strain at the instant of maximum...

Hello, I have followed the input data as written and i get the exact same results as stated in the table, respectively 7200 & 2970, so my guess is that somewhere you must have missed the units...

Hi, Is possible modeling fatigue analysis which include chemical environment ? For example: fatigue of tooth, where acts Chemical substances.

My mistake. I forgot the Force Per Unit Area Distribution!
View ArticleRe: fatigue which include chemical environment
Usually the environment is accounted for via an extra stress factor. But this is very tricky business. You cannot just say that a certain chemical has a factor of X. The factor will be different for...

Thanks all for your help. I came up with a solution,Just to clarify the question. The part am analysing does not come into contact with the floor. It's a sheet metal part mounted inside a rugged...

Depends on your tools. How are you currently calculating fatigue?

I do not have that luxury, so I have to go on what i read and see. You could (ab)use the surface finish and try different settings, and then compare it to test results. But this is sort of a black box...

Re: How to make a analysis on oak
The only difference that I could see between your model and mine was the modulus (E). You have 12.15 GPa, and I have 11.0 GPa. I changed mine to 12.15 GPa and my displacement is now 19.3 mm (I think...

If I use shells I also get results of 19.8mm, so not how Ruben got to 11 13.1mm. Maybe it is because he distributed the loads over a small area, instead of using point loads?

Excellent....beam tool or shells...produces same results.
