Effects of initial shape perturbation on wavelength, subcortical growth, and stress in the 2D elliptical (cylinder) model with a compressive target stress in the outer core. Initial radial growth in the core was attained with Eq. 15 with F(R, θ, τ) = F0τ cos kθ for τ < 0.1. Columns: Initial radial growth Gr at τ =0.10; radial growth Gr; tangential growth Gt; radial stress σr; tangential stress σt. Row 1: F(r, θ, τ) = 10τ cos 32θ for τ < 0.10, shown at τ =0.90. Row 2: F(r, θ, τ) = 10τ cos 8θ for τ < 0.10, shown at τ =0.60; Row 3: F(r, θ, τ) = 50τ random (r, θ) for τ < 0.1, shown at τ =1.2. In all rows ΓG = 0.20.
