so meaning to say the CFRP can stretch the same way as steel? ain't they brittle ofcoz with nonlinearity unlike metals which tend to break than stretch

can CFRP laminates deform like metals when subjected to for example internal pressure resulting in shape change then, if so is it also influenced by the type of ply stacking

everything seems to be on point yet the same problem persists

Excessive incremental rotation of the elements in element set ErrElemExcessIncrementalRotation-Step1. There is only one element with excessive rotations Abaqus/Explicit Analysis exited with an error - Please see the status file for possible error messages if the file exists. i have revisited...

multiple errors i used dynamic explicit to run the simulation but since composite behave diferently than metals i ahd to create laminate composite the result is unrealaistic i dont know where i am getting it wrong

i have been facing problem with tube hydroforming of composites in abaqus with regular metal i ahve no issue i reaaly dont know where i am getting it wrong please assist

@SWComposites @FEAway thanks alot let me look into it

thread799-336484 hi been looking for material properties for CFP but i can find them anywhere. Thank you will be helpful

hello again sorry i made all my modelling and BC but i dont know why its still not finishing the simulation below i have attached my cae file please help if there is a possible error on the file greatly appreciate your...

for the excel on calculating strain values. the modelling part is ok i manage to finish it, its material excel values that i dont really know how to calcalate. thank you

hI was wondering if you can offer some help on this question how you calculated your values THANK YOU The blank is made of aluminum-killed steel, which is assumed to satisfy the Ramberg-Osgood relation between true stress and logarithmic strain, ε=(σ/K)^(1/n) with a reference stress value (K)...
