Fig. 4.

Circumferential (top and middle) and axial (bottom) Cauchy stress–stretch relationships for both the contracted (black circle) and relaxed (gray square) states for Fbln5^+/+ (solid symbols) and Fbln5^−/− (open symbols) groups and at the studied pressures and axial stretches. The direction of changes in Cauchy stresses ($\Delta {\sigma }_{\vartheta },\Delta {\sigma }_{\mathrm{z}}$) and stretch ($\Delta {\lambda }_{\vartheta }$) due to isobaric and axially isometric contraction are marked with black arrows.
