    composite properties

    Dear All, I am trying to model a composite material. I have the properties along the fibre material but when I need to input the properties of material model I can only do it for the x and y axes. Is it possible to change the orientation of the axes? If so how can I do it? Many thanks in...

    hourglass controll - improve running time of jobs

    Dear all, I am performing an analysis which is very long (at least 7 days) and needs to be improved. I am modelling a quarter of the plate with a crack which is propagating from the centre with a very fine mesh and a cyclic load applied. The material is plastic. There are any option in ABAQUS...

    Restart a finish analysis from a defined step

    Dear all, Is it possible in ABAQUS to start an analysis which has already compleated from a defined step adding different load and condition? Thanks in advance, Albert

    post precessing in abaqus like patran

    Dear all, Is there any way in ABAQUS to read a results file of nastran or any other processor and post process it in ABAQUS CAE? Thanks, Albert

    undo with abaqus

    Dear all, Is there any undo command for abaqus? For examples I delete a part in my model from the tree scheme in CAE but I want to undo my action. Is it possible to recor the part that I just delete? Thanks, Albert

    convergence problem with contact analysis

    Dear all, I have some convergence problem with a contact analysis. I run the model of a quarter of the plate applying a cyclic load for each node. After one cycle I release the node from its symmetry and I apply the cycle at the following node. I put an analytical surface in the symmetry line...

    extract data from odb file

    Dear all, Is there any method to estract the data from an odb file? For example I would like to extract the stresses value along a certain path wich I have to define from the odb file. But I have to search for different step as well and that will be a very long process if I have to doit...

    S4R plane strain plane stress condition

    Dear all, I am doing a plastic analaysis using S4R elements. The previous resutls show that the S_op will change wheather using plane stress or plane strain condition. I search on the manual but I could not find weather S4R can be considered as plane stress condition or plane strain condition...

    node numeration

    Dear all, I would like to know if there is a way in ABAQUS to re-numerate the nodes. For example re-numerate the nodes alogn one line. Thanks, Albert

    elastic perfect plastic- cyclic load

    Dear all, I am doing an elastic perfect plastic analysis applying a cyclic load. I am doing a quarter of plate with a notch in the centre applying symmetric boundary condition. I am loading 10% of the load each time and so for the unloading. I can not finish the analysis becase of convergence...

    material overlapping

    Dear all, I am modeling a crack which starts from the edge of a plate with a hole inside. When the crack reaches a certain distance behind the crack tip there is a mterial compenetration. How can I avoid this over closure effects? thanks a lot, Albert

    thermal analysis

    Dear all, I would like to make a thermal analysis by inputting a tempreature as a load and see the following distribution of stresses. When I create a new step I choose the option to make a coupled temperature-displacement analysis which give the option to choose some heat flux rather then a...

    contact

    Hallo everybody, I would like to know how to make a contact with a plate and a line with rigid elements. The erroro message says me that some elements are not defined. Such elements are that one of the line, but they are rigid elements. Which kind of properties I should apply? Thanks, Albert

    crack growth

    Hallo everybody, I would like to know if is possible with abaqus, simulate a crack growth. If I put a cyclic load how can I say to abaqus to release the nodes? is there any way? Thanks, Albert

    non linear geometric

    Hallo everybody, I want to try to make a non linear geometric analysis with abaqus. I have a distribution of stresses and I would like to apply a Load step by step in order to see how the load is going to redistribute the stresses every step. Is it possible to make a non linear for different...

    franc2d residual load

    Good morning, does anybody know how can I input residual load with franc2d? in the manual is written to create a file *.rsi but how can I write the residual stress field? Thanks a lot, Albert

    write a series of file

    Hallo everybody, I would like to write a series of file where they are different only for the name, like name_1, name_2,name_3 ecc... what I'm doing is something like this: do j=1:50 open(unit=2,access='sequential',file='name_'j'.inp',status='old') end do how can put the J in the name in...

    Deviation of crack

    Dear all, I have to model a plate with a whole and a crack that start from the edge of the plate. How can I see how the crack is going to deviate? From assembly-crack-I can modified the q vector that is the direction of the crack but how can I get the right direction? thanks, Albert
