Spatially Varying Material Properties for Hollow Cylinder

    • Chee Min Leong


      I am trying to vary the young's modulus of a hollow cylinder. In my case, the Young's modulus decreases radially.

      I followed the instructions here
      for a cube and applied it to a hollow cylinder.

      Since the model I am working with is symmetrical, I have set up quarter symmetry and my final result is shown below.

      Figure 1 - Source Points & Score

      Figure 2 - Material Plot 

      Figure 3 - Young's modulus vs Score


      Figure 2 shows the young's modulus changing radially but the minimum value is not 1E+9 as shown in figure 3.


      So, my questions are,

      1. Why is the minimum value not what I wrote and how can I fix it?
      2. How many source points do I need to map the material properties accurately?


      Please let me know if you need more information.

      Is the 'r' value 100 where you expect 'E'=1E9 Pa? Also, if you have the nodes numbers, their location then try using the E values with node number and location for mapping the material property.
