hi
Thankyou to everybody that helped.
As suspected the supplied values were incorrect.
It should of been E = 169GPa and a force of 100uN was, of course, too large for the poor beam. So the instructor told us to choose an appropriate value for the force (wish he had told us this 2 weeks ago when...
Hi nvn
E = 1.69 GPa.
I agree the values are strange. The material is supposedly silicon, in which case E should be more like 169GPa and v ~ 0.25
It would also be nicer if F = 100nN. I have questioned the given values to our lecturer but received no response, which tends to mean my...
Hi Mapes
I get 1.278m, it has been checked, other students in my group had the same result. Either way, 13mm is too large as well. Is there an alternative to E-B using the supplied values? Or should I just report the cantilever is in snapdown/maximum deflection?
It is the first I have heard...
Greetings
I am trying to understand the greatly differing results between calculating the theoretical deflection of a cantilver and simulating it in ANSYS.
The cantilever is 1 um thick, 5 um wide and 300um long, one end is attached, the other end receives a force of 100uN in the y-direction...
