Tendons transmit forces from muscles to bones. We and other mammals depend on them for moving our limbs. But, although they are so important, the mechanical properties of tendon tissue remain poorly understood. The constitutive behaviour is complex, with pronounced nonlinearity, viscoelasticity, and anisotropy; tendons’ irregular geometry complicates experiments on them; and they can show wide scatter in properties. Recent research has aimed at overcoming these problems, to achieve improved characterisation and understanding of the 3D deformation of tendon tissue. This has required progress in several areas: a new method for capturing the 3D geometry of tendons; tensile tests with a new approach to interpreting the results; a new approach to testing tendons in lateral compression; and the first testing of tendons in axial torsion, with and without superposed axial tension.  Combining results from all these tests provides improved knowledge of the 3D deformation of tendons, and helps interpret this in terms of what is known of their structure.
