    Burst Pressure of a Class 125 and a Class 250 cast iron fitting?

    I would like to know a "general" guideline for the burst pressure of a Class 125 and a Class 250 cast iron fitting? I have looked into ASME B16.4 and it does not mention what the burst pressure is, or what the assumed safety factor is. I am just looking into obtaining some information on the...

    Friction Heating.....Thermal Seizure Question

    I have a question concerning the potential for frictional heat generation to cause the seizure of a shaft within a bore? My issue involves a punch becoming stuck within a bore during a compression punching operation. I believe the issue is a lubrication issue where the frictional coefficient...

    Creating An "Assembly" Between DesignModeler and Classic.

    I am trying to create an "assembly" between a Design Modeler geometric component and a geometry being created in ANSYS classic. A colleague of mine has created a portion of the overall geometry in ANSYS Classic. Since I am more comfortable creating the component in ANSYS Design Modeler, I...

    "Find" Output Notation

    I have a simple question regarding the mathematical syntax of my "Find" output. I am trying to solve a system of three equations symbolically and I am getting a parametric conditional solution I believe. The mathematical syntax is not exactly clear to me (although I am a newbie to the Mathcad...

    Preventing RBM when contact is the only restraint

    I am looking to prevent rigid body motion in a contact analysis problem where the contact is the only restraint against an applied load. This is a generic question concerning general procedures used by members of this forum, although I also have a specific example I am concerned with. I am...

    Biaxiality Indication Plot in ANSYS Classic

    Does anyone have a macro (or method) for plotting the biaxiality indication in ANSYS classic? This is basically a ratio of the principal stresses. I know it can be done as Workbench has this in its Fatigue Module, but I am having some difficulty with it in the Classic interface.

    Initial/residual stress due to shot peening process

    I am trying to apply some initial compressive stress to the surface of a casting due to the shot peening process. I was wondering if anyone has any experience with this? I am looking to apply this initial stress as a function of depth into the surface. Does anyone know if this is possible...

    Extracting a pressure distribution from contact

    After performing a contact analysis, I would like to extract the applied pressure distribution on the contacted surface for use as an applied load on a different component with an identical contact surface. The nodal locations will not necessarily be identical. Is there a method for obtaining...

    Graphics/Performance question

    When solving a problem in ANSYS classic, I can not minimize the screen. Similarly the "show desktop" key has no effect. Does anyone have any idea as to the reason for this? We recently upgraded to x64 machines, could this be the problem? Also, this issue does not occur with Workbench, only...

    Minimal Supports reaction loads

    When using balanced loads and the 3-2-1 minimal support scheme, what type of reaction loads would be considered acceptable? The goal, at least in my opinion, is to have zero reaction forces and moments at these nodes, but that would seem impossible due to the necessity of having a reaction...

    Implicit Dynamic Analysis (Impact) - WBv11

    I am trying to perform an impact analysis where the load is applied suddenly (delta t ~ 0.01 s). I am obtaining results where the maximum stresses developed are 100 times less than the static case for an identical load, which to me should not be the case. Does anyone have any experience in...

    Bolt Contact

    When modeling a bolt inserted into a hole, what is the "best" method to handling the contact if the bolt and the part are both solid models meshed in Workbench 10.0? For this particular case the bolt consists of a head, shaft and thread. I am concerned with the stress within the bolt (preload...
