    Bending moments transfer through adhesive bonded joint

    Hi respected engineers! I face a design issue in which i would like assistance due to my lack of experience. I want to connect a CFRP tube with metal inserts at each edge (the metal fittings are of smaller diameter than the CFRP tube and length of 33mm into the tube) and the proposed joint is an...

    Restart Analysis - Femap 11.2.2 with NX Nastran

    Hello eng-tips friends! Today i realised that i don't know how to run a restart analysis in NX Nastran! The software is updated, so i work on Femap 11.2.2 with NX Nastran. I wanted to run a prestressed frequency response model, so in order to do that i had to run a nonlinear modal analysis with...

    Preload in Modal Analysis - Restart

    Hi everyone, I use Femap v.11.1.2 with NX Nastran 9.0 and i face a rather difficult problem. First of all i have a structure that i want to use in a frequency response analysis, but before that i run a modal analysis so that i can use these results for restart in frequency response...

    Viscoelastic material properties

    Hi everyone, I am using Femap 11.1.2 and i wanted to use the SDAMPING card referencing TABLEDi in a direct frequency analysis (S108) in order to express the damping of a viscoelastic layer as a function of frequency. This procedure is explained in Nastran Advanced Dynamic Analysis Manual in...

    Honeycomb panel - Modal analysis

    Hi there! I am using Femap v.11.1.2 with NX Nastran 9.0 and i am currently working on modelling a honeycomb panel consisting of aluminum core and Carbon Epoxy laminate faces. I have decided to proceed with modelling the faces qith QUAD4 elements along with PCOMP entry (laminates) and solid...

    Radiation Analysis

    Hi everyone, i use Femap 11.1 with NX Nastran v9.0. My basic license includes Steady state Heat Transfer and i would like to use it to perform a radiation analysis with sun as a source to a truss in orbit (although i analyse the structure being at a specific point). Is there a capability of the...

    Large rotation-maneuver analysis

    Hi everyone, I have a truss structure connected with two large masses (large compared to the truss), one at each side and i want to rotate the whole structure 60 degrees from the original position, around the CoG. My input is a profile of constant acceleration for 300 sec, then constant...

    Parametric Analysis

    Is there a way to write a script in Femap API that creates and solves many load cases in one run? More like a parametric analysis of different analysis cases with a varying property of the model.

    Modal analysis of rods with nonlinear material

    Hello i am a new member at this forum and i would like to get some help regarding a question i have. I have a truss structure with cables which i model as rod elements with nonlinear material behavior (high tension stiffness and very low compression stiffness). I would like to have a boundary...
