For eacg parts i have done many things, such as partition, tie, coupling, mesh. I can not merge the model because each component...

    Crack propagation under compression load

    Dear You see, in crack propagation analysis, we have three way to model (please take a look in ABAQUS MANUAL), and in each method, we have to define some parameters and these will affect to the crack propagation. Such as Normal failure stress, shear failure stress (with CRITICAL STRESS), or...

    IMPACT

    Dear i don't understand for the deformation plot factor, and don't know where to check it? anyway, my problem close to ex "crusing of tube" in ABAQUS/explicit: keywords. I do the same thing for my model, the above problem happened. I come back to do again ex by ABAQUS CAE, the tupe also freely...

    Crack propagation under compression load

    Dear I have done with it before, and i got the same problem. Then i see that, the load will not effect much to propagation of crack. Just take a look at the others parameters when you define this step.
