Hello, Does anyone has experience in making a substantiation report regarding the creation of cutouts in a floor panel? I have a few ideas how to approach this presuming i have the data about the honeycomb core and the fasteners used to fix it to the floor. - Try to find the loads that the...

Hello, I have a question for people who have experience with designing,calculating and testing honeycomb panels/structures. I want to know what are the steps in the Design process of a honeycomb sandwich panels structure. I have a structure subjected to a gravity load. I make an FEM model...

Hello , i would like to clarify some things. Perhaps you could help. I am trying to make some FEM analysis about some examples in Bruhn and BDM abou buckling of plates. I want to take those examples and compare the results obtained analytically with the ones form FEM. But i a have some...

Hello, I would like to hear some experiences of some of you guys with the design,analysis and testing of honeycomb structures. I am not interested in how to analytically analyze a rectangular panel or how to model it in FEM.....you can find that in every book. What i am interested is what are...

Hello, I have stumbled on a issue , regarding the design of sandwich honeycomb panel structures. I have no problems in designing and making the analysis for rectangular plates , as for Bruhn and BDMs are more then enough and clear, but as long as your inputs are known. My structure is a...

I am trying to make an axisymmetric mesh of a cylinder shape, very simple.I have the revolving section of the cylinder. Does anyone know how do you mesh that surface with axysimmetric elements like CQUADX4, 8 or CTRIAX3 or 6? Because i can fin these elements in the help manual describing their...

Hello everybody, I have a small problem using CGAP elements. I use NX 7.5 and trying to output the reaction forces but when summing up the forces i have they are not the same with the Loads. I am using CGAP elements in a linear analysis with SOL 101. Solution parameters used: AUTOMPC YES...
