    warning messages in implicit analysis

    hello everyone, I am modeling the axisymmetric tube hydroforming of aluminium tube by implicit analysis, the pressure is varied upto 22 MPa For higher pressure from 15 MPa onwards I get the warning messages The strain increment has exceeded fifty times the strain to cause first yield at 1331...

    input material data

    Hello, I want to input material properties of AlMg3 alloy for hydroforming process. I have put the data points from the stress-strain curve in L direction in mechanical > plasticity > plastic . I have the value of R0,R45,R90 so i can obtain R11,R22,R33,R12 and put in sub-options > potential...

    Coupling between pressure and deformation in tube hydroforming.

    Hello, I am trying to simulate tube hydroforming process in abaqus,i am using axisymmetric model of the tube. The coupling between the pressure exerted by the contained fluid on the tube inner surface and the deformation of the tube can be modeled using (incompressible) hydraulic fluid elements...

    hydroforming of carbon nanotubes reinforced composites.

    hello. I want to know if hydroforming process is applicable in forming of carbon nanotubes reinforced composites or any other metal forming process that can be implemented, as I want to do a finite element analysis on the above subject. thank you
