SUMMARY:Thesis Defense: Paul Simanjuntak\, Physics\, Astronomy &amp; Materials
  Science
DESCRIPTION:Development of Many-body Potential for Deformation Study in\n\
 n\nAl-TiN Nanolayered Composites by Paul Simanjuntak\n\n\nA novel interat
 omic potential of ternary Al-Ti-N has been developed to study the deforma
 tion behavior of Al-TiN nanolaminates. The ternary nanolayered Al-TiN com
 posite has attracted a large interest due to its combination of strength 
 and ductility.  \n\n\nThe current analysis on the system has been primari
 ly concentrated on continuum models which are inadequate to explain the k
 ey deformation events such as nucleation and interaction of dislocations.
  Progress in the preferred atomistic approach has been hampered\, however
 \, by the lack of available interatomic potential optimized for the terna
 ry system. We developed a many-body potential based on Embedded Atomic Mo
 del (EAM) by employing the force-tting code Pott to sample the energy and
  force data generated from the ab-initio molecular dynamics simulations o
 f the ternary system using VASP code. \n\n\nFaculty and students are invi
 ted to attend this graduate thesis defense. Paul Simanjuntak is a student
  in the Materials Science program\, and Dr. Ridwan Sakidja (PAMS) is his 
 research advisor.
