Fig. 7.
Changes in strains of SMLs and ELs in the radial–circumferential plane during pressurization. Upper row: a cumulative circumferential normal strain εθθ, b cumulative radial normal strains εrr and c absolute value of radial–circumferential shear strain |εrθ|. Lower row: d incremental circumferential normal strain Δεθθ, e incremental radial normal strain Δεrr, and f absolute value of incremental radial–circumferential shear strain |Δεrθ|. Data are shown as mean ± SD. Number of mice = 1;*, P < 0.05 versus EL
