"WebFoam materials are generally not used for applications where tension and shear loading are dominant. However, they are usually used where compression loads are expected. The most attractive feature of foams is the ability to undergo a large strain deformation while maintaining a low constant stress level before the densification region [22]. " - Foam spring constant
