Compressed cylindrical shells are common in our daily life, such as rolled-up sleeves and a retreated package of drinking straws. The deformations on these cylindrical shells with a rigid core are often random and unpredictable. In contrast, compressed beer can exhibit uniform arrays of diamonds, called the Yoshimura pattern. To elucidate the difference between these systems, we combine molecular dynamics simulations and experiments to study the deformation on a compressed cylindrical shell with a rigid core. By thoroughly exploring different material parameters, we are able to pin down the mode diagram.
