has a Young’s modulus of 7 MPa. All the material sets have a zone 2 Young’s
modulus of 7 MPa. Material sets 14, 15, 16 and 17 have a zone 3 Young’s
modulus of 7 MPa. The zone 4 Young’s modulus of materials sets 15, 16 and 17
is also 7 MPa. With so many of the material sets having a low Young’s modulus,
the authors expected the deflection bowls to extend beyond point 17. This was
the case with all the deflection bowls extending to point 22. The 100% deflection
value was determined from points 23–29 for all the group 3 material sets.
