Intrinsic and Extrinsic Deformation of
Micro- and Nano- Polymer Composites
 
This research program is aimed to link macroscopic and microscopic deformation with structural changes induced in the polymer matrix on reinforcement with micro- and nanoparticles during tensile, compressive, and scratch deformation. Primary issues concerning deformation and fracture are being addressed.
  • How nanoparticles interface with the polymer matrix and if there are molecular structural changes because of the adoption of nanoparticles?
  • What is the nature and contribution of the interface (interface strength) and length scale effects?
  • Is delocalization of yielding a controlling factor in understanding the toughness of nanoparticle-reinforced polymer composites?
  • How are the micro- and nanoscale deformation mechanisms influenced by reinforcement with nanoparticles in relation to neat polymers?
Simultaneously, computational modeling methods are being applied to simulate structure and properties and their response to applied stress.
