[Mechanical function of the liver capsule]

Histomechanical experiments were performed on human and bovine liver capsules. On strain processes, the mechanical resistance force increases slowly at the beginning, and then with a continuous change rapidly. The relaxation processes approximate to a constant form at equal stains with interponed isometrical phases. This indicates that the tissue has a trend towards a viscoelastic equilibrium (balance behaviour, steady state). In further experiments the following histomechanical properties could be demonstrated: Upper and lower summit decrease at dynamical (cyclic) relaxation, and cascade dynamical (cyclic) force recovery with stepwise reduced force amplitudes.
