A nucleation theory for yielding of nearly defect-free crystals: understanding rate dependent yield points
Vikranth Sagar Reddy, Parswa Nath, Jürgen Horbach +2
Experiments and simulations show that when an initially defect free rigid crystal is subjected to deformation at a constant rate, irreversible plastic flow commences at the so-call…

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…
