Hello,
I'm having a conceptual problem here. I have a multilayer beam that was tested under a 3 point flexural bending using ASTM D7264. The standard provides the formula of flexural stresses for a quasi-isotropic beam where the load "F" from the test is used to calculate stresses. In my case...
Dear Jerry.
Yes, the weaves end faces can move inward as it just a representation and is completely parametric, but would it lead the interpenetrations to resolve? I'm trying to understand the physics behind your recommended method. [ponder]
Thank you very much.

Hey Jerry.
Thank you for the suggestions. Yes I tried both of your recommendations but unfortunately, the body intersections still remain. I don't know how can I remove them. Is there a way to locally move the edges of the faceted weave (the edges which surround the places of body intersection)...
Dear Experts,
I'm trying to perform a subtraction boolean operation on my geometry, but the boolean operation fails with an error message- "Unable to perform boolean". I have tried to see visually, that my geometry has body intersections but I don't know how can I solve these? The body is...
Dear Tomas,
Yes, these bodies are made up of small triangular faces. I want to remove those small "interferences" between the bodies firstly and then find a way to smoothen the surface i.e. maybe try to merge triangular faces into to form one monolithic structure in this case 12 smooth...
Dear Tim,
The file is in .stp format only. Yes it is a faceted model. I'm trying to create a 3D model using sew geometry option. Can the interpenetrations be solved after "sew" operation?
Thanks

Hello Experts,
I have this geometry of a composite fabric generated from an external software. The CAD model has numerous overlapping geometries or intersections. I have tried to work with "Heal Geometry" tool but it doesn't work in this case. Is there any way to solve this problem?
You can...
Toost aka Tomas, you are just too good with NX. :) Kudos.
Just an additional question. Is there also a way to make a negative CAD in NX.
I have tried to make the freeform shape as a solid body by sewing the sheet body shape but I would also like to fill the bounding box and behave like a...
Dear All,
Thank you for the kind suggestions.
Tomas, the model is indeed small and is not a translation error. The model originated from a composite modeling software called as TexGen. The dimensions of the part file are as specified and required. The freeform shape is more like a yarn...
Dear Users,
I want to do a subtract boolean on my model in NX12. I have two solid intersecting bodies, but I cannot perform it as it gives an error which prompts me to "examine geometry". How can I get over this error? I have uploaded my part file. The part is generated externally and then...
Dear Experts,
I would like to calculate the stress intensity factor for layered composite material. I'm trying to use KCALC command but it doesn't seem to work. Is there any other suitable method?
Dear MarkosMark,
You need to have a deformation matrix (Hooke's Law). The elements are elastic tensors. The values can be found in any research paper dealing with carbon fiber at Meso-Scale.

Dear Experts,
I'm trying to export NASTRAN 101 structural results as a .sim and .fem file for further study. How can I do that? Is there any method in NX10 or a script that helps to do that.
Regards
