Hi, I'm doing an linear buckling analysis on a composite turbine blade.
Now the certification organisation states that the use of the layered shell91 element, does not result in reliable values.
They advise the use of shell181 in order to obtain reliable results.
Now am I aware of the need to...
After spending much time in the Ansys help, I'm not able to find anything about specifying the Tsai-Wu failure criteria.
Ansys help describes that there are 3 pre-programmed failure criteria, stress/strain/Tsai-Wu.
But I cannot find the way to specify that I want to use the Tsai-Wu criteria.
Can...
Hi,
Im modeling a nacelle cover of a windturbine, using layered shell-elements.
Now I how to model some stiffeners in the nacelle, and want to have a nice transition from the plates to the stiffeners.
In practice this is done by using tapered foam between the layers.
Now I've tried to model this...
I'm modelling a bolted flange and have to pre-load the bolts.
In the past I used temperature dependent properties in order to obtain an specific pre-tension force.
But I've read something in the help about specific pretension elements. Are they easy to use or would it be wise to stick with the...
