    problem with abaqus standard Convergence after normal loading of half sphere shell (buckling)

    I attached the model just run it on bucle step to find the first eigne value and you will see what I am talkin about it's like you apply the load on one direction and you get bucling on the opposite direction

    problem with abaqus standard Convergence after normal loading of half sphere shell (buckling)

    I need to apply a pressure nor a displacement , my friend my goad is to find the displacement

    problem with abaqus standard Convergence after normal loading of half sphere shell (buckling)

    it's like this, exactly like this . how to do so and what is the arc size I donc know about these procedures

    problem with abaqus standard Convergence after normal loading of half sphere shell (buckling)

    thank you I 've tried the buckli,g step technique but when the simulation completes it gives me a non sens buckling results it gives it on the opposite direction. I'll attach the CAE model with the buckle step and everything . I tried to overpass the buckling by adding an other material in the...

    problem with abaqus standard Convergence after normal loading of half sphere shell (buckling)

    Hello Ings I'm getting a problem reaching convergence with a half spherical empty solid ball when applying a normal load on its external surface leading to divergence when the shape deforms to reach a certain point of displacement ; this drives me crazy , I've read that this could be buckling...
