Bulge test at nano-scale: The surface effects

Submitted by tongqing.lu on
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 size-dependent behavior. The present theoretical model is in quantitative agreement with the molecular dynamics simulations.

Challenge of Biomechanics

Submitted by Konstantin Volokh on

The application of mechanics to biology
– biomechanics – bears great challenges due to the intricacy of living things.
Their dynamism, along with the complexity of their mechanical response (which
in itself involves complex chemical, electrical, and thermal phenomena) makes
it very difficult to correlate empirical data with theoretical models. This
difficulty elevates the importance of useful biomechanical theories compared to
other fields of engineering. Despite inherent imperfections of all theories, a
