fiber reinforced concrete modeling
hi everybody.
i want to simulate and modelling fiber reinforced concrete in abaqus. but i don't know and i can't how to do it.
how can i simulate the fibers in concret?
please help me in this case.
thanks

I want to define the expansion coefficient alpha as a function of the depth, alpha(z)=f(z). How can I achieve this in UEXPAN? I cannot find a way to incorporate coordinates in UEXPAN.

Hello
brothers
Currently,
I‘m working on the determination of the mechanical properties of carbon nanotubes
for different loading cases using ANSYS software ( i need to use them in my
model). My Finite Element model of graphene and carbon nanotube is working fine with beam188 element, but I have
some technical problems in my simulation. These problem are summarized in
points as follow;
abaqus
Hi
i want to add a stress relation to abaqus
can i write it in fortran in a way that i can enter specification like c11-c12-....in abaqus then have the calculation of stress in fortran and bring back the result in abaqus to analysis?
load effect in ansys
hi everyone;
we know that axial load effect on dynamic responses of structur ( for example comparsion axial load decreas frequencies) and Modal analysis does not depend on load too.
i want to obtain dynamic responses for simply supported beam under axial load. How do modal analysis in the presence of axial load in ansys (How apply effect of axial load)???
plz help me
Deep Rolling simulation in ABAQUS
Hi all
I want to simulate the deep rolling process(as seen as in attachment)
in this model I defined 2 steps,at first, the rigid ball create a pressure to cylinder to create residual stress and at the second step the ball begins displacement with
a low speed in direction of cylinder longitude to create surface overlap, while the cylinder is rotating in both steps.
in this model I have used the explicit solver but it takes too much time and elements convergence cannot be accomplished.
how can i reduce the time of my solution?
