Quick question: Orthotropic elastic material properties in Workbench

    • cheng089413

      Dear Community,

      Just a quick question about material definition inWB

      As shown below, I am wondering the poisson ratios input in WB are in terms of major poisson ratios or minor poisson ratios? 

      Or it strictly follows the order the how x,y and z is arranged. Assume x is the strongest material axis, then Poisson Ratio xy is major, and YZ is major one as well, XZ is also major. Is my understanding correct?

      Thank you!

      Yes, the entries are major Poisson's ratio.

        Hello Ashish, appreciate you answered my second question in this post and thank you for your time!

        I am still confused about the MP entries here. What if the z axis is the strongest material axis? If so, isn't it poisson ratio yz and xz minor ones?

        Or say it can only assume in WB MP entries that x is the strongest and not allowed for other axes to be the strongest ones? 

        Thank you for your help!

        Kind regards!
