摘要

In this work a numerical study is developed via Abaqus software that describes the undulatory elastic behavior of arc-shaped metallic glass (MG) ribbon subjected to normal progressive loading. The pre-deformed ribbon is prepared based on the experimental condition which should ensure the initial amplitude hover the boundary fixation L less than 1/2. The objective is to estimate numerically the maximum number of undulation that the arc-shaped ribbon could reach before plasticity. The control and estimation of the elasticity becomes very difficult when the miniaturization is requested. This result is very interested when the elastic undulation response of MG ribbon will be used as a flat spring or electromechanical switch for micro-machines and Micro-Electromechanical Systems (MEMS). The obtained numerical results are compared to the experimental available data and we have found a good agreement. This numerical study is done for the first time on the metallic glass ribbon and the improvement of the obtained results is in progress.
