论文简介
Bulge test is an effective technique to measure the mechanical properties of thin films. As the
membrane size decreases to nano-scale, the surface effect plays a significant role in
determining the mechanical behavior of the membrane, and the techniques commonly used
to measure the bulk materials properties are not applicable. We explore the surface effect on
the nano-scale bulge test using combined continuum theories and atomistic simulations. We
formulate the load-deflection relation by incorporating the surface effect and analyze its ...
