yes bad design to have the 90 degrees, and i definitely didnt take out a fillet out of there, the fillet is still there actually. its the way it was manufactured to have that 90 degrees effect. cant manufacture it directly but it can be a byproduct of the manufacturing process? an...
csk62 & jhardy1 :
guys i understand what you guys mean, it was pointed out by rb1957 & corus. thank you for further emphasis regarding the matter. i was trying to introduce a new facet to the thread. i should reword the statement,
"why i would like to know the exact stress at that point?" to...
thanks all for your replies, getting more clarity out of these discussions.
rb1957 :
yes there is a counterbore breaking the edge
this model is different from the first stress figure we were discussing about, i used a nonlinear model for this. agree that linear model for this is not the way...
corus :
just to clarify myself, geometric stress concentration are the ones as in handbooks, exp: a rectangular block with a hole in the center?
could you elaborate what you mean by a point load and restraint causing a stress concentration? any examples to illustrate?
the picture in my 2nd...
thank you all for your replies,
I guess using a linear material model to assess a component with a stress concentration can only be used to identify the stress concentrations or give an idea of how the component behaves under the loads and boundary conditions its been placed on.
or like what...
Hello Everyone,
I am currently working on a linear static FEA with stress concentrations. I have not refined the mesh on the stress concentrations. The average stress in another region/surface without the stress concentration from 2mm-9mm mesh size has shown consistent output of about 30MPa...
