markers
To show (internal) mechanical tissue stress at membrane internal air pressures of 10
and 20 mbar, the normal stress component S
33
and the shear stress component S
13
have
been evaluated along path 5 (tailbone to skin) and path 6 (coccyx to skin) beginning at
the point of maximum normal and shear stress, respectively, cf. Fig.
7.34
.
