    problem with contact pairs in abaqus

    Hi all, I have a semicone with two different friction coeficient (Coulomb law) the first half part of the semicone is frictionless and the second is 0.2, A material is formed going through the semicone and I am not sure how I should define the contact because apear appears a warning...

    Aluminum, plastic behavior at high temperatures

    Hi, I would like to implement plastic behavior at 480 ºC. I got those results with Ludwik law: Plastic stress= 50 MPa K 400 n 0,17 E 35500 and plastic data is: Stress Strain 50 0 60 0,00140845 70 0,00140847 80 0,00140869 90 0,00140976 100 0,00141332 110...

    Problem with material definition

    yes.. sorry, i forgot to look for the young, the idea is to to simulate hot aluminium and i found for 480ºC it is about 32200 Mpa and aldo I am not sure how to obtain data for plastic area, I just sow from a grafic it is start in about 50 MPa but the rest of the data i'm not sure, I'm using...

    Problem with material definition

    Hi!! Thank you, I tried to remove intermediate poinst and also i tried to put more points but alwais apear the same error... Also I didn't find "specific material types". I dont know what happen, if somebody can have a look to my CAE would be great!! I attached the document. Regards...

    defining crosshead speed

    I'm not sure about that but firstly I would define the suface where i supose it is running to an expecific speed and after that i would define the speed (Load > Boundary condition manager > create > displazament/rotation )

    Problem with material definition

    Dear people, Any idea how I could solve this problem ???? When I submit my .CAE appears this Error ... ----------- Failed to regularize material data for material ALUMINIO. Please check your input data to see if they meet both criteria as explained in "MATERIAL DATA DEFINITION" section of...

    why don't flow the aluminium thought

    I tried to simulate an extrusion of aluminium thoght a form, the billed is compresed but the aluminium don't go thought the form, any idea what could happend?? I attached the document PDF with many pictures of every step i...

    ABAQUS: 125257 elements have missing property definitions and partition on a curved surface

    I'm trying to simulate an extrusion and i dont know why i have any deformation, i attached the CAE , in this Cae there is not die, only appear the billed with the boundary conditions, http://files.engineering.com/getfile.aspx?folder=2cd06917-43ff-4e6f-9da2-5590d9b1a22a&file=extrusion_de_mierda.cae

    no, I didn't I atached the filehttp://files.engineering.com/getfile.aspx?folder=d156ec13-7020-4474-86db-40a2e7c0dc1d&file=Placa_Y_Soporte.cae

    ABAQUS: 125257 elements have missing property definitions and partition on a curved surface

    I already did, after that i did a paar of partitions, maybe it is because those partitions? When you do a partition, it is like a new part??? is the material properties uncouple ??

    ABAQUS: 125257 elements have missing property definitions and partition on a curved surface

    125257 elements have missing property definitions, I don't know how to start or how could I solve the problem, My idea is to simulate the deformation of a plate die and the bolster. On the plate die there is a presure of 300 MPa and on the bolster there is a constrain oposite to the presure...

    submit failed in implicit analysis

    I show in the picture the warning message, i don't know how i could fix up this mistake or what could I do to solve this. Thank you people!!!http://files.engineering.com/getfile.aspx?folder=bbc01286-eb52-4b85-bf3c-ceb48dc16b88&file=Sin_título.png

    How to implement boundary condition in a cylindrical part

    thank you for your reply Mustaine3, I tried to do that and the thing i'm not sure is the position of the edges Ur = U1? I mean the numerical and the normal names, Thank you!!!

    How to implement boundary condition in a cylindrical part

    I have a cylinder and My problem is that I want to implement a boundary condition of free displazament along the edge, but radially lock the displazaments, and i only know how lock the displazament long x, y or z, but not radialy. Thank you!!!
