Anyone involved with the engineering of rubber products is probably already aware of L.R.G. Treloar.  He is famous for a variety of papers on rubber physics beginning in the 1940s. An early paper, often cited is:

Stress-Strain Data for Vulcanized Rubber Under Various Types of Deformation

Transactions of the Faraday Society, Vol. 40, No.2, pages 59-70, February 1944.

The Wikipedia link for Professor Treloar is here.   Treloar published a seminal book on the physics of rubber behavior :

L R G Treloar (1958), The physics of rubber elasticity, Oxford: Clarendon Press, cop., ISBN 978-0-19-857027-1

This book was reprinted several times. 

In his papers and his book, Treloar showed some simple tension (ST), planar tension (PT) and equibiaxial tension (EB) test data for a 8% sulfur rubber.  This test data has been used by many researchers, especially in calibration exercises for testing hyperelastic material models based on various energy potentials. Some researchers were fortunate enough to obtain an original copy of Treloar's test data, others digitized this data from figures in his papers.  We were fortunate in obtaining a copy of Treloar's original test data from another giant in this field, R.W. Ogden.  The attached Excel spreadsheet contains this original test data from Treloar.  The spreadsheet also contains Treloar data from Abaqus Example problems, and some digitized from the literature (just for comparison). 

On September 19, 2020, the 3DExperience public (aka 'Customer Cloud in Production') cloud was upgraded to R2021x FD02 (FP2032, HotFix 2.2). This version contains all of the calibration app functionality of R2020x FD04 (FP2030).  The demonstration video below uses this Treloar test data and performs a few simple hyperelasticity calibrations.  The purpose of this video is to provide a simple first introduction to the material calibration app with a simple end-to-end use.

The video below is similar to the one above, but it was created using the 3DExperience version R2018x from the Fall of 2018.
