      Hi all,

      I am new to ANSYS and I need it for my MSc project. Can anyone guide me on how to use it to simulate 45S5 Bioglass coating on Titanium and compare it with another sample but with an additional coating of Amdry powder. Finally, I want to conduct the bending, compression and tensile tests?

      Hi, what's the exact goal of your simulation? To determine coating properties, to investigate coating-substrate interface quality...? The mechanical tests you listed are conducted experimentally, numerically, both? Do you have already some information about your materials? For your simulations, you need to know few things: coating thickness, quality of interface (low or high adhesion...)... and your model (geometry/mesh) might depend with the type of test you are doing and what you are looking for (elastic analysis or fracture behaviour...).

      Thank you sir

      My goal is to compare the adhesion strength at the coating - substrate interface with and without the powdery layer.
      For the test, it will be numerical and compared to existing experiment from literature or can experiments be performed on ANSYS?
      What are the information required for the materials?
      what types of tests are available on this package, like i said earlier I am new to this package and wish to use it
      For the coating thickness I will get that from the existing literature
      Fracture behavior will be a focus, because the research deals with the durability of 45S5 Bioglass coated on Titanium for biomedical implants

      The best for you might be to use Ansys Workbench and Mechanical to perform parametric studies.
      Here some reference paper:
      https://www.semanticscholar.org/paper/FEM-simulation-of-three-point-bending-test-of-718-Singh-Tyagi/54aedc4183d1edaed3156528801d7f1917472d20
      https://link.springer.com/article/10.1007%2Fs11666-020-01041-6
      Then you have some discussions on the Ansys Learning Forum:

      And a video about modelling bending test:

      The 1st step should be an elastic analysis, for that you need elastic modulus, density and Poisson's ratio of each material. You can find some inputs in Granta EduPack / Selector or MDS:

    Thank you so much sir I have read through those papers and found them very useful, I also watched the Youtube video link which has led me to other channels.
    However, I am still facing a difficulty of downloading the student's version of ANSYS. I keep having error messages.
    Please enlighten me on what to do.
    Thank you for your usual assistance

    Great if those links can help you. About student version of Ansys, I advise to have a look into this forum: https://forum.ansys.com/categories/ansys-free-student-software
