Abstract
Certain, in situ mechanical properties of the hinge-ligament of Anodonta cygnea L. are described: 1. The ligament consists of elastic and viscous elements. A plausible equivalent is given. 2. A crude Young-modulus for the quick, elastic compound is: 2.8 ± 1.8 kp/mm² 3. The tensions developing in the participating ligament and adductors during the closure of shell: T (muscle) 0.03-0.04 kp/cm² (minimal) T (ligament) 1-1.5 kp/cm² (maximal) 4. Dynamic constants determined for a linear approximation of the freely moving shell-ligament system are: frequency ~ 30 Hz; К ~ 7.2 -10⁵ dyn/cm; damping: ~ 0.1; D ~ 754 dyn·sec·cm⁻¹. 5. The elastic ligament can be one of the causes of the in situ observable relaxations and it is in a part responsible for the initial value laws described for the adductor muscles (Lábos et al. 1970).
