    Material for plastic deformation

    Hello guys, I am trying to simulate plastic deformations with Optistruct and I am struggling to find the proper material card image. I have all the data (values for true strain/true stress), young's module, isotropic, solid metal etc. As far as I understand it should be non linear since we have plastic deformations (?), no change of temperature or heat. I really appreciate any help or advice :-) Cheers
  2. Hello, is it possible to define a new material in AFDEX? If I have a special purpose material, what is the data required and how can I do it?
  3. Hello, i have a Problem with a buckling Analyse: There is a Aluminium Piece with three bores. In each bare there is a RBE3 with Loads and moments in every direction (xyz). The model is fixed by PARAM AutoSPC=YES and INREL=-2. The question is: How much plastic Deformation will be left after the load is being applied and than decreased to 0... I tried it with two Non-Linear quasi-static loadsteps and MATS1 Material as a table. The Analysis is runing until 50-60% of the load is reached and than gives this error: *** ERROR # 4965 *** Maximum number of time increment cutbacks reached, analysis aborted. It appears because 5 approaches to correct the foregone load increment. It seems, that the plastic Deformation starts at that Point and it expands extremly fast: Starting load increment 88 Current increment 9.8192E-008 Subcase 6 Load step: 5.5889E-01 -------------------------------------------------------------------------------- Nonlinear Error Measures Gap and Contact Element Status Maximum Iter Avg.

Does someone already had this Problem or some advice for this sort of buckling analyse? Thank You and best regards HyperName
