Influence of the degree of mesh refinement on the final buckled strip shapes. (A) The total strain energy and maximum von Mises stress mostly converged for the three inspected mesh densities. (B–D) Shapes and energy profiles for $3\times 3\times 300$, $4\times 4\times 400$, and $5\times 5\times 500$, respectively. The geometric parameters of the strip are $w=3\hspace{0.5em}\text{mm}$, $h=3\hspace{0.5em}\text{mm}$, $L=30\hspace{0.5em}\text{cm}$, and $L\prime =L/3.5$.
