    connecting skirts to cylinder made of composite

    Hi everyone I have faced a major problem. I don't know how to connect skirts to composite cylinders containing gas. It does not matter what is the skirt made of.

    cohesive data retrieving

    Hi everyone, I have defined a cohesive element, everything is ok, but I don't know how to retrieve how many elements of cohesive part are torn by scripting, although I've tried to read abaqus manual script. Is there any way?? like, a code to return whether an element SDEG is equal to 1 or not...

    Cohesive Element

    Hi everyone I have defined a model for cohesive element trying to determine SDEG result of a structure. After submitting the job and observing the results, I don't know why the red part which is standing for the torn elements is not continuous and it's presented in different pieces as shown by...

    Abaqus results (deformed shape)

    Hi everyone I have run a model consisting of only one 2-D part. I don't know what the reason of reaching that kind of result at the end is... It's like two 2-D sheet lying on each other... The right image is the deformed one. Does anyone know what the reason is ?? Thanks by the way

    Defining a cohesive interaction

    Currently I'm using abaqus 2020. I've tried to define contact interaction but It's not possible due to having only one object. I don't know whether if it is possible or not to define an contact interaction between elements located on a predefined 2D sheet. I cant do that, however I have tried to...

    Defining a cohesive interaction

    I tried to use "find contact pairs" but it gave me this massage : "Axisymmetric and 2D models are not considered in contact detection." I don't know what to do... because elements edges are not recognized as contact

    Defining a cohesive interaction

    Hi everyone At first, I've defined a square sheet and then partitioned it to generate a set of 64 element. I want to make a cohesive interaction between every elements, I mean on the line which they are attached . My question is that, is it possible to do so or I should try something else...

    Auxetic material modeling in abaqus

    Thanks But I have another problem which is, I don't know how to model a negative Poisson's ratio. I mean I'm not sure whether abaqus accept it or not, because I am not familiar with subroutine writing and I searching for a simple way of defining negative Poisson. So after all, can you suggest me...

    Auxetic material modeling in abaqus

    Hi everyone, Is there any Plugin available for modeling Auxetic material in abaqus? If not, what is the way of modeling auxetic without subroutine? By the way, thanks for answering

    J-Integral scripting

    I don't know why the code below does not work ! Jint= odb.steps['Step-1'].historyRegions['Assembly ASSEMBLY'].historyOutputs['J-Integral'].data I have determined 5 contours for my J-Integral how do I fine the code??

    J-Integral scripting

    Hi at all I am trying to calculate j-integral for 5 contours by abaqus script, and although I have tried to find in user manual of abaqus, I didn't find anything useful. I know its as simple as writing one line of code, but I don't know what to write. Can anyone help me with a line of code?

    Abaqus saving out-put by scripting

    Hi every one I have run a set of jobs in abaqus and I want to assign the Max. of ALLIE of each job as a list array by scripting. I don't know how to do so although I've checked the abaqus user guide... Does anyone know the command to save it as in a list ?

    hi at all I've defined a set of jo

    hi at all I've defined a set of jobs in abaqus, but it runs them all at the same time. I want it to start a new job after the previous one is completed. Is there any command to force it do so ?

    How to measure toughness and strength of a composite in crack fracture

    I have faced another problem. If I want to get ALLIE and ALLSE, I have to put the domain in the history output on " whole model" instead of "crack". If I do so, the job does Not submit cuz It says you have to use J-integral due to presence of crack in my composite. So, how do I get ALLIE and ALLSE ?

    Hi at all I have a problem in runn

    Hi at all I have a problem in running my abaqus script. Although It worked well when I was designing it in abaqus visual environment but now, when trying to run the generated script, I face an Error called " NameError: name 'Q_VECTORS' is not defined ". It's about a seam to model a crack... What...

    How to measure toughness and strength of a composite in crack fracture

    That is wonderful. thanks by the way. But one more question, as I searched it is possible for an element or a node and so on... But, is it also possible for the whole model??? I mean the total energy absorbed by the model before failing... And one more thing, is it any available example of this...

    How to measure toughness and strength of a composite in crack fracture

    Thanks Maybe I didn't explain correctly . actually my question is " can I calculate toughness(the area under the stress-strain curve) by abaqus?" before the moment that my structure fails. may be this picture works better. there is a seam in my 2D composite . I mean how much energy does it take...

    How to measure toughness and strength of a composite in crack fracture

    Hi at all I've got a problem, actually I don't know from witch part of abaqus, I can measure the toughness and strength of a composite before the crack fracture. I mean , shall I determine any specific output in STEP module ??? By the way I use the contour integral crack modeling. If any one...

    Abaqus scripting

    thanks but one one question , shall I use the x-y coordinates to find a specific cell?
