    Hoop stress

    This is my model. I have found that (in one element) X stress = 67.7 MPa Y stress = 334 MPa Z stress = 11.1 MPa How can i calcul hoop stress ?

    composite progressive failure

    I have assigned the material to the elements. When i used linear static solution i don't have any error but when with implicit nonlinear patran/msc nastran 2012 I have found this message : USER FATAL MESSAGE 2016 (IFP6) NO MATERIAL PROPERTIES EXIST. 0FATAL ERROR

    composite progressive failure

    I'm trying to simulate the progressive failure of a composite tube under tensile test with ortotropic properties, using implicit nonlinear solution (sol 400). I have entered linear elastic properties and failure1 (sol 400/600) with maximum stress failure criterion and progressive failure option...

    Composite failure

    My model is a filament wound composite cylinder (9 layers (0/0/0/55/-55/55/-55/55/-55) resine vinylester/verre E. I'm modeling a tensile test of the tube and i would like to obtain the behavior of the tube after failure.

    Composite failure

    I'm using Patran 2012/MSC nastran to calculate total damage for a composite tube but when i got the result i don't found total damage for progressive failure of a composite. I just found failure indice, critical components reserve factors and margins of safety. Should i using MD nastran instead...

    Laminated Modeler

    I would like to use tool BUT when I try to select it I can't because they are "grey" and I can't select it. Do I make something wrong? Should I do something before select it to activate it? Or Laminated Modeler is not included in my license??
