Recent experiments have revealed diverse and sometimes conflicting deformation behaviors of vertically aligned carbon nanotube arrays under compression, but a thorough understanding of this phenomenon is still elusive. Here, we employ a mesoscale bead-spring model to demonstrate that the seemingly complex deformation behaviors of carbon nanotube arrays can be understood from competing elastic and adhesive interactions at the micro scale.
