    Simulation of three-dimensional cracks (2000)
    Springer
    The visual computer 16 (2000), S. 371-378

    Notes: We describe a method for simulating the process of cracking based on a 3D physical model. Cracks appear when the stress caused by internal or external force exceeds the tolerable amount. We applied a spring network model to a simulation of cracks that appear on drying clay. Clay contracts, or shrinks, as it dries. Because the surface part dries more quickly than the interior, the stretching stress acts on the surface part, generating cracks. The process of drying changes physical characteristics such as stiffness and maximum strain. Our model introduces the properties of clay by defining these parameters as functions of time on the basis of measurement.

    Effect of disuse on the ultrastructure of the achilles tendon in rats (1989)
    Springer
    European journal of applied physiology 59 (1989), S. 239-242 
    Details
    ISSN: 1439-6327
    Keywords: Collagen fibre ; Achilles tendon ; Disuse ; Atrophy ; Ultrastructure

    Notes: Summary We examined the influence exerted, through disuse of the hindlimb, on the collagen fibres of the achilles tendon in rats. With disuse the body mass decreased by 28%, and the mass of soleus muscle decreased by 20%. A decrease in the surface area and diameter was observed in the experimental group when compared to the control group. A histogram of the collagen fibres showed a decrease of the thick fibres in the experimental group. The maximum surface area of collagen fibres in the experimental group was seen to be only 43% of that of the control group. These results showed a decrease in the thickness of the collagen fibres of the achilles tendon through disuse. This seemed to suggest that resistance to tension is decreased by disuse.
