Evolution of wrinkling patterns for Type I (\(\frac{{\boldsymbol{t}}}{{\boldsymbol{H}}}=\frac{1}{30},\frac{{{\boldsymbol{\mu }}}_{1}}{{{\boldsymbol{\mu }}}_{0}}=1000\)) and Type II (\(\frac{{\boldsymbol{t}}}{{\boldsymbol{H}}}=\frac{2}{15},\frac{{{\boldsymbol{\mu }}}_{1}}{{{\boldsymbol{\mu }}}_{0}}=100\)) under three stages of equivalent biaxial compression (global strain ε = 0%, 2%, 4% (Type I), and ε = 0%, 8%, 16% (Type II)).
