Hi,
Do you know any approach or subroutine to modify the thickness of shell elements (3d shell) through a nonlinear analysis?
I am using the implicit solver.
Thank you.
Hi,
I want to model damping in a dynamic analysis in Abaqus explicit. So I can do it by material damping and Rayleigh damping; however, there is another option as bulk viscosity that default parameters are 0.06 and 1.2 as you can see in the attached figure. They can affect dynamic responses. Do...
I want to model concrete beams in Abaqus explicit that doesn't support *Rebar . I also cannot use solid or shell elements due to the scale of the structure.
I chose to create 2 beam elements for each part ( a beam with a rectangular section for concrete and an I-section beam with a near-zero...
Hi everybody,
I need to model the nonlinear behavior of a large reinforced concrete structure but not with detailed solid elements. Is there any possibility in Abaqus to use beam element (like Hughes-Liu in Ls-Dyna) and define rebars inside?
Thanks
Hi,
Do you have any reference about the function Abaqus uses for boundary response interpolation in the submodeling technique? I checked the documentation, it doesn't mention the type. Is it only a simple linear interpolation or does Abaqus use the element shape function for interpolation...
Hi everybody,
I am trying to mesh a rectangular plate with hexahedral elements (not tetrahedral) in Abaqus. But one side of the plate is covered by elliptical pits as shown in the attached figure (pits are random in place and geometry). As a result, the Abaqus mesher can not do it automatically...
Hi,
I am trying to apply the mass only on one edge of a shell but the option "Mass per length" is not applicable to the shell edge. Do you know any trick for that? Thanks in advance.

Hi everybody,
I am modeling a coupon test in which the end of the specimen is pulled to a certain displacement. I am using the explicit solver and I used amplitude to define the displacement. But when I did the analyses the output showed that the specimen wasn't pulled to exactly the final...
Hi everyone,
Is it possible to do a displacement control analysis based on a differential displacement between two nodes? I mean I want to apply the displacement in a reference point until the differential displacement of two other nodes reaches a certain amount. I appreciate your help in advance.
Hi,
I want to apply an incremental cyclic displacement with a tabular amplitude in an implicit analysis but the output displacment of the controlled node is not the same as defined amplitude. The number of cycles and the shape of cycles is different from input displacement (please see attached...
Hi,
I need to do structural-to-structural co-simulation. I have a 2D frame as my explicit model and I need to couple this frame with a 3D joint as a submodel to study the behavior of the joint. I defined three nodes as Abaqus/Standard co-simulation interaction points but I need some more info...
Hi,
I need to know the reaction forces of a specific node at the end of each increment to use it in other subroutines. I found that URDFIL could be a solution but it was difficult to manage it and I could not find a good tutorial to explain how it works. Do you know any other method (subroutine...
