Laminated glass in ABAQUS

[dkhc]

Hi, I am currently doing a project on analysing laminated glass elements under different types of loading. I am planning to analyse the laminated glass elements over a range of PVB interlayer shear modulus (0.001 N/mm^2 - 100 N/mm^2). I am going to use 3D solid elements for both glass and PVB interlayer. For the material properties, I am going to use E=70000 N/mm^2 and v=0.23 for glass. My difficulty is what material properties I should enter for the PVB interlayer if I am treating it as a linear elastic material.

Thank you
