F.E.A

[SolidCreative]

Can someone explain how to read this F.E.A test? It appears that there is more deformation at the bottom of the part then at the top. It might be I’m confused about the idea of deformation and displacement. I thought this chart would tell me how much the part would physically bend under the loaded condition?

Not sure exactly what your boundary conditions are but it looks like you have an L bracket restrained at the "bottom" with a load applied somewhere along the vertical member. The greatest displacement/deformation being at the end. Sort of like a diving board. Seems logical to me. Maybe I'm missing something.

SolidCreative,

It looks to me like you are running CosmosWorks under SolidWorks. The coloured areas show the value of deformation, with the small values at the (solidly supported?) bottom, and the large values at the top, the end of the cantilever. It makes sense to me. The bulge in the blue area is not deformation. It is the line at which the deformation is 2.272e-5.

Try doing a stress diagram. Your maximum ought to be at the interface between the base and the vertical section. The stress should be zero above your force arrow.

It looks to me like you have your magnification set to 1. Set to a big number like 100 or 1000, and you will see an exaggerated version of the actual deformation.

Other than that, I hope you know what you are doing.

yeah, sorry folks. This was just a mistake in reading, like;y cause by a summer long weekend. I thought that 2.2e-5 was larger then 0.0002 for some reason.

Thanks for the help though
