    Stress Allowables in tension

    Thank you. I have supposed the same.

    Stress Allowables in tension

    What is the meaning of Stress Allowables in tension in the material definition? Is it used in any simulation? Irwin

    FEMAP model - Temperature dependent plastic material definition

    Hallo! Just for clarification: Basically my target is that: with temperature dependent material definition. What and where should I write in FEMAP to get such results in sol106? The best would be a FEMAP example file. BR, Irwin

    FEMAP model - Temperature dependent plastic material definition

    Hello Blas, After several trying some errors what I can not change: User Warning Message 4675. User fatal message 4676. (I think these are coming from the same issue.) I hade one simulation where I had got results. From this analysis I have made just one modification, a constant temperature...

    FEMAP model - Temperature dependent plastic material definition

    Dear Blas, I have no error. I have no idea how I could define any temperature dependent non linear material in FEMaP for transient simulation. I would like to analysis a structure where I have stres-strain curves on different temperature level and temperature and force load which gives us...

    FEMAP model - Temperature dependent plastic material definition

    Hi Everybody! I would like to make a non linear analysis whith FEMAP/NX Nastran which contains the following material definition: - Temperature dependent Young modulus - Temperature dependent Stress-strain curve - Temperature dependent conductivity - Temperature dependent Poisson number I have...

    Temperature dependent young modulus

    How could I generate a material wich is temperature dependent. I have tried on several tests the temperature dependent material, but it seems it is not working correctly. Could anybody send me a NEU file which is correct? BR, Irwin

    Linear vs non-linear temperature dependent material

    I have tried the follwoing: 2 models with same mesh, force and temperature load and constrains. The only difference is the material definition. First model contains simple material definition for linear static load: E, nu, alfa and Tref The second one is a little bit different: The E is...

    non linear temperature dependent material

    Is it possible to define temperature dependent stress-strain curves for a non-linear steady state or transient simulation?

    Transient anaylsis

    I have temperature distribution at 0 s and I have another one at 1 s and another one at 2 s. Is it possible to use these temperature distributions as transient load for stress analysis? If yes how? Where can I find a turorial or example?

    Primary/Secondary stress or Fatigue analysis

    So what is your suggestion? Gravity and Temperature load for simple primary and secondary load approach and independently fatigue analysis for wind and independently fatigue for the acceleration loads? Or something else? Anyway: In which chapter I can find this info what you mentioned? I

    Primary/Secondary stress or Fatigue analysis

    An example: I have the following loads: - gravity (1g) - temperature - extrem wind load - extrem horizontal acceleration (+-0.16g) - extrem vertical acceleration (+-0,23g) How should I define load combinations and limits? Do you have any addvice? E

    Primary/Secondary stress or Fatigue analysis

    Do I understand well, if I have static load in this case I should use primary, secondary analysis method, if I have dynamic load I have to post-process everything according to the fatigue method? Ervin

    Primary/Secondary stress or Fatigue analysis

    Maybe I was not accurate in the question. In the DIN EN13445 standard there is a description about primary stress and secondary stress analysis on pressure vessel structure in the Annex C. In the Chapter 17 and 18 you can find a description about a fatigue analysis method also for the pressure...

    Primary/Secondary stress or Fatigue analysis

    Dear Everybody, I would like to know in which case should I use primary/secondary analysis method and in which case the fatigue SN curve analysis during a pressure vessel analysis? Irwin

    Sliding bearing limitation

    Dear Everybody, I would like to know more about the limitation of sliding bearings. What are the maximum values for total pressure, asperity contact and unit loads for 2,3 layered bearings and sputter bearings? What would be the minimum oil film thickness? Have somebody any catalog of...

    Node plot

    Yes! That is my feeling also! Regards, Irwin

    Node plot

    Any other idea? How can I switch on during the mesh or load definition? E

    Node plot

    I used also this very uncomfortable mode. Does anybody know an option to plot the nodes without numbering?

    Node plot

    How can I plot just nodes to check them in ABAQUS CAE? Irwin
