Reverse Engineering – Chemically Treated Waterlogged Wood

  I am trying to find material properties for a waterlogged chemically treated 500-year-old piece of timber.
  (this is to help for the design of a support structure so the ship can be displayed in a museum).
  
  I have set up the timber in a lab to test its deformation under self-weight for approx 6 weeks with the aim of modelling this so that through trial and error of editing the material properties, the deflection results will match that in the lab.
  
  Is there a way of modelling these parameters in ANSYS???
  
  I initially had a go, but found no way of adding such a long time to the model.

  Hi Joshua,
  
  If you have stress strain data then try using a hyperelastic response function: How to Set Up Response Functions for Hyperelastic Material Models — Lesson 2 - ANSYS Innovation Courses
  I am assuming that all the deformations would be in elastic region.
