Hello,
I'm doing a large deflection analysis with BEAM4 elements but I'm having difficulties plotting the axial rotation due to torsion. The normal rotx DOF plot gives erroneous results because it is based on the nodal coordinate system instead of the element coordinate system. I tried...
Hi all,
A string of pipe elements clamped one side and loaded with a torsion moment results in a certain amount of rotation. Now I'm wondering if adding a tensile force to the pipe's free end results in a lower amount of rotation.
I tried to simulate this very simple problem in Ansys but...
Hello all,
I'm doing a large deflection analysis with a string of PIPE20 elements. I want a force to work in the pipe's axial direction at any time during the analysis, hence I need a follower force. I know this requires applying an axial pressure since forces in Ansys always point in the same...
Hello all,
For some time I've been trying to predict the occurance of rotation in a pipeline with an initial curvature, when bent in the opposite (against the initial curvature) direction. My assumption is that when you try to 'straighten' a curved pipe, it will try to rotate 180 degrees at a...
My questions is the following:
Consider a supersonic flow over a flat plate at angle of attack. The flow direction downstream of the trailing edge of the plate, behind the trailing edge shock and expansion waves, is not precisely in the free stream direction. Why?
Apparently there's an effect...
