Polymer stress growth in viscoelastic fluids in oscillating extensional flows with applications to micro-organism locomotion [PDF]

open access: yes, 2019
Simulations of undulatory swimming in viscoelastic fluids with large amplitude gaits show concentration of polymer elastic stress at the tips of the swimmers.We use a series of related theoretical investigations to probe the origin of these concentrated ...

Crack initiation site at the interface between a nano-component and substrate

open access: yesMechanical Engineering Journal, 2014
In order to determine the effect of triple junction on the crack initiation, we use the finite element method to investigate the effect of misorientation between Cu grains on the stress concentration near the triple junction in comparison to that near a ...
