Three different numerical formulations of the confined compression creep of cartilage have been developed to study the feasibility of applying numerical methods to dynamically loaded joints in biomechanics. The accuracy, convergence and stability of these numerical methods are assessed. Extensions of the analysis to include joint lubrication and non‐uniform properties are discussed, and an example is given of cartilage under dynamic load conditions. It is found that with the amplitude of loading maintained constant, the deflection of cartilage reduces as the frequency of load application is increased.
