M.T. Petre , A. Erdemir & P.R. Cavanagh (2006) Determination of elastomeric foam parameters for simulations of complex loading, Computer Methods in Biomechanics and Biomedical Engineering, 9:4, 231-242, DOI: 10.1080/10255840600747620

This paper is very interesting in part because the authors also shared publicly a large quantity of resilient foam test data.  The test data is for a large set of foams, and includes uniaxial compression, simple shear and volumetric compression testing.  The paper also makes the point that just testing a foam in uniaxial compression, then calibrating, may create a material model that behaves very incorrectly in shear.  It is also uncommon to see volumetric testing performed on a foam, which the authors do by way of a very interesting test apparatus (see video).

This Excel file contains just the "Poron cushioning" test data in Excel.  This test data was averaged by the authors and the column was omitted.  I have used the data as if time is quasi-static. 

Here is all of the data, in its original form (.zip file):

Here is the author's video of their volumetric testing device:

3D Experience Calibration App

The video below shows how to use our 3D Experience calibration app to calibrate the hyperfoam material model using this test data.  The hyperfoam functionality shown was delivered in the on-premise 2020X FD02, aka FP2014, release.

Here are their calibration values from their Appendix B, Table B.1

                                                              Mu         alpha     beta       nu

Poron                    UC          1             0.620     34.46     0.040     0.0370

Cushioning          UC+ SS 1                0.144     4.013     0.057     0.0512

Here are the responses from the app, using their parameter values (for UC only).  This matches their Figure 2 (upper row).    This is not a calibration from me, just using their parameter values. 

Here are the responses from the app, using their parameter values (for UC+SS). This matches their Figure 2 (lower row). This is not a calibration from me, just using their parameter values.
