    NON-LINEAR, LIMIT LOAD ANALYSIS: DESIGN OF EXPERIMENT (TABLE OF DESIGN POINTS) CONTINUOUS RUN

    All, I am running a non-linear limit load analysis [LLA] in which I am taking my model (geometry and material model) to plastic collapse. I am performing a design of experiment (DoE) in which I am varying a set of design parameters to assess the maximum burst pressure my component fails at...

    Elastic-Plastic Analysis - Determine the maximum load for a burst test

    Hello all, I'm using ANSYS 18.2 Workbench Enterprise. I am running an elastic-plastic analysis in accordance with ASME VIII Div 2 Part 5 where I wish to determine the maximum pressure load at the point I am predicting the design to gross plastically collapse. Is there an easier and more...

    ENGINEERING TO TRUE STRESS VS STRAIN DATA

    Hello all, I have a set of mechanical tensile test data in which I wish build material models in ANSYS. I have Tensile Strain (mm/mm) data and Tensile Stress (MPa) data. These are Engineering Stress/Strain values provided by our testing house (raw data). I am however looking for True...

    ANSYS SPACECLAIM - Attempting to paste 2D sketches on to planes

    Hi everyone, Is it possible to paste a 2D sketch created in Autocad on to a 2D plane in Spaceclaim? The Autocad file is essentially the master template so that can't be changed. I would like to import that .dwg file on to a specified plane in Spaceclaim, then, apply a sketch profile to the...

    APPLYING FORCES/MOMENTS

    All, Does it make a difference in Caesar when you specify the direction of the force and/or moments, or does Caesar run the analysis for both positive and negative components of the same force...

    Importing Parameterized Catia model in to ANSYS Workbench

    All, 1) I am working on a design of experiment (DoE) in ANSYS. 2) I created a parameterized model in Catia V5. 3) I wish to be able to pull in those parameters defined in Catia in to Ansys so the DoE can run as per a usual DoE experiment. 4) I have already converted the Catia Product...

    Constraining AutoCAD-imported sketches in CATIA on to planes of parts

    Hi all, Apologies in advance if I am asking a repeated and past question. 1) I am attempting to constrain a sketch which I have imported from AutoCAD by importing to Catia Drawing then copy and paste on to Catia Part model - complete. 2) The sketch itself is made up of thousands of...

    PD5500 Reactor Vessel: A requirement for bolt loading calculations with an O-ring seal.

    [Please refer to attachment throughout] Dear fellow users, I'm validating a reactor vessel design as per the client's requested design code [PD5500]. Essentially I have three parts to this simple assembly - backing plate, shell and front plate - bolted together and sealed around the peripheral...
