The free energy of grain boundaries from atomistic computer simulation
Saswati Ganguly, Jürgen Horbach
A novel thermodynamic integration (TI) scheme is presented that allows computing the free energy of grain boundaries (GBs) in crystals from atomistic computer simulation. Unlike pr…
Do thermodynamically stable rigid solids exist?
Parswa Nath, Saswati Ganguly, Jürgen Horbach +3
Customarily, crystalline solids are defined to be {\em rigid} since they resist changes of shape determined by their boundaries. However, rigid solids cannot exist in the thermodyn…
Plastic deformation of a permanently bonded network: stress relaxation by pleats
Saswati Ganguly, Debankur Das, Jürgen Horbach +3
We show that a flat two dimensional network of connected vertices, when stretched, may deform plastically by producing `pleats'; system spanning linear structures with width compar…
