Hi,
I have a quick global to local submodelling question. I have an Abaqus model and that all works fine on my computer. I've followed the instructions of Referring to the global model results from the submodel analysis so that it correctly locates the global results file.
The problems arises...
Hi guys,
I am sure there are many of you who have done a 3D bolted joint model. At the moment I am trying to validate my FE model, and so I am currently using this paper to benchmark my results:

Three-dimensional finite element...
Hi,
Does anyone have any experience about how to find the forces acting on a joint that is subjected to an out of plane load? For example I have a square panel that I want to attach to a frame around the perimeter, so I would like to work out the corresponding joint loads in shear and tension...
Hi,
I have created an Abaqus model which uses the Fasteners connection type to join two surfaces. The fasteners have been defined as attachment points. Is there a way I can get a free body cut specifically for the nodes that the attachment point is connected to? I know how to generate a...
Hi, I’m trying to validate my FEA models by using experimental stress-strain data from a composite tension test. I’m using NEI Nastran but for some reason the FEA results are way too stiff. I thought initially it was a material model issue so then I changed to an isotropic material – aluminium...
Hi, has anyone tried performing classical laminate theory in reverse, i.e. getting lamina stiffness and strength values from experimental laminate data? I have been attempting to do so but I can’t seem to get my formulation to work correctly. I’m 99% sure it is correct because I can go from Q...
Hi
I want to determine the optimal layup for a carbon composite frame structure but I am new to composite finite element modelling. So far I have just been setting up simple geometries analysing static and buckling load cases that I have been comparing against an aluminium model.
The...
Hi,
I am using the automated impact analysis module of NEI Nastran with Femap to model a drop test for a container. To reduce the complexity I have decided to model the corner of the container in isolation. Now this container is going to contain cargo that I want to simulate as a rigid mass. I...
