software

Hi All,



I am trying to model a simply supported reinforced concrete beam with longitudinal reinforcement. I am using 8-node solid elements for the concrete, and 2-node truss elements for the longitudinal reinforcement bars. I have embedded the reinforcement bars in the concrete using an Embedded Region constraint. I am then applying a displacement at the midspan (deflection control). I am using the Concrete Damaged Plasticity model for the concrete. My model begins to run but will not converge. Some of the error messages that I get are:

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;
