    How to calculate absorbed energy in a material during impact?

    Energy summary make perfect sense. How then to derive the absorbed energy from ANSYS? Thanks

    How to calculate absorbed energy in a material during impact?

    Hi, I have a hollow tube is being impacted by a block of 25 kg at 14 m/sec along its longitudinal axis. I am using INT_ENERGYALL results option in ANSYS Explicit and I've selected the tube as my body. The problem is: the calculated result is way too high - (1.13 e5 J/kg)~ 11515 J for the 0.108...

    How to plot a composite failure index in FEMAP?

    I'm starting to do analysis of composite structures in FEMAP. I wonder how to plot a failure index e.g. Tsai-Hill or Tsai-Wu. I will also be grateful if one could point me to any resources on the subject of composite modeling in FEMAP. Thanks H

    What is the purpose of holes in chassis frame longitudinal members?

    Hi, Can someone please, tell me: What is the purpose of holes in chassis frame longitudinal members? Someone suggested that they are reducing the chassis weight, another suggested that they are to allow for homogeneous distribution of the stresses along the members. Thank you, H

    How to parameterize a cad model in ANSYS?

    Hi, I've built a CAD model of a sports car space frame in Solid Edge. I wish to optimize the structure in ANSYS. In other words, I want to import the CAD model(iges) in ANSYS and make parts thicknesses as parameters. Hence, be able to change these parameters in an optimization algorithm. Any...

    Road roughness effect on dynamic loads

    Hi, I am looking for a way for measuring road roughness and its effect on the dynamic loads on vehicle suspension. Is there a whole system for measuring both responses simultaneously? Thank you, Hesham

    How to export part file to iges?

    I have a part file that contains lines only, and I want to save it to an iges extension so as to use it in ANSYS or FEMAP. I cannot export it because it contains no solid bodies Any ideas? Thanks

    Export part file to iges, igs

    Thank you Sebastian, However, I have no solid bodies in my file, therefore I am getting an error message and no files are exported. H

    Export part file to iges, igs

    Hi, I have a frame.par file that contains a 3D sketch of lines representing a car space frame. I want to export the frame.par to a FE software such as ANSYS for modeling. I cannot export the frame.par file to another extension such as iges, igs,...etc. An error states that the file contains no...
