We propose a mechanical model to account for progressive damage in collagen fibres within fibrous soft tissues. The model has a similar basis to the pseudoelastic model that describes the Mullins effect in rubber but it also accounts for the effect of cross-links between collagen fibres. We show that the model is able to capture experimental data obtained from rat tail tendon fibres, and the combined effect of damage and collagen cross-links is illustrated for a simple shear test. The proposed three-dimensional framework allows a straightforward implementation in finite-element codes, which are needed to analyse more complex boundary-value problems for soft tissues under supra-physiological loading or tissues weakened by disease.

The purpose of this note is to comment on some models for the mechanical properties of tendon and to draw attention to a misprint in an earlier paper, Diamant et al , (1972), to which we were contributors. In the study published in 1972 we and our coauthors at Case Western Reserve University, Cleveland, Ohio, presented optical and mechanical evidence for a planar zig-zag model of the basic load-bearing structure in rat-tail tendon interpreting the mechanical deformation by the theory of the extensible elastica. Because of an unfortunate misprint in the published paper, the validity of the elastica model has been called into question, and other theories explaining the load deformation behaviour of tendon have been proposed (Lanir 1978; Comninou & Yannas 1976).

The load-strain and stress-relaxation behavior of wet rat tail tendon has been examined with respect to the parameters strain, rate of straining, and temperature. It is found that this mechanical behavior is reproducible after resting the tendon for a few minutes after each extension so long as the strain does not exceed about 4 per cent. If this strain is exceeded, the tendon becomes progressively easier to extend but its length still returns to the original value after each extension. Extensions of over 35 per cent can be reached in this way. Temperature has no effect upon the mechanical behavior over the range 0–37°C. Just above this temperature, important changes take place in the mechanical properties of the tendon which may have biological significance. The application of the techniques used here to studies of connective tissue disorders is suggested. Some of the mechanical properties of tendon have been interpreted with a simple model.
