Table 1.

Cartilage specimens used for testing protocols. Thickness of the femoral head specimens used in the testing of articular cartilage in air / in Ringer’s solution and thickness of the humeral head specimens used to analyse stress dependency of the viscoelastic properties; the diameter of these specimens was 5.2 mm. Humeral head core specimens used to analyse the effect of the restraint of bone on the viscoelastic properties; the diameter of the core specimens was 4.1 mm.
