ABSTRACT A constitutive model is developed that incorporates the wavy elastic response of an arc-shaped metallic glass (MG) ribbon subjected to applied progressive normal load. This model is based on the evolution of the angle made between the buckled ribbon and the horizontal plane. It predicts the amount of elastic strain preventing the yielding of material when it is used as a flat spring or electromechanical switch for MEMS (Micro-Electro-Mechanical Systems) and NEMS (Nano-Electro-Mechanical Systems). The numerical solution of the constitutive equations resulting from the model is compared to experimental results and shows good agreement. This present result is useful for miniaturised ribbons since the estimation of the elastic strain in these was previously quite difficult.

金属玻璃带波浪弹性响应的本构建模

摘要 开发了一种本构模型，该模型结合了弧形金属玻璃 (MG) 带在施加渐进法向载荷时的波浪弹性响应。该模型基于扣带与水平面之间夹角的演变。当它用作 MEMS（微机电系统）和 NEMS（纳米机电系统）的板簧或机电开关时，它可以预测防止材料屈服的弹性应变量。由模型产生的本构方程的数值解与实验结果进行了比较，显示出良好的一致性。这个目前的结果对于小型化的条带很有用，因为以前很难估计这些条带中的弹性应变。
