Fig. 9. Worm thickness for model 2 in gelatin and in natural sediment with
calculated stresses. The solid line is the worm thickness in gelatin (green
dotted line in Fig. 8), with
pharynx stress of 378 Pa and body stress 92 Pa, linearly decreasing to 60 Pa.
The stresses were increased in natural sediments by
Esed/Egel to a pharynx stress of 5305
Pa and body stress 1291 Pa, linearly decreasing to 842 Pa (dotted line).
Because the change in Poisson's ratio was not considered, the calculated
stresses resulted in higher displacements. Stresses were reduced by the ratio
of the displacements in gelatin to the displacements from the first stresses
applied in sediment, to pharynx stress 4408 Pa and body stress 1073 Pa,
linearly decreasing to 700 Pa (dash-dotted line).
