DESCRIPTION:FRETTTING FATIGUE: Damage due to fretting fatigue is a major c
 oncern in gas turbine engines. We have focused on the development of crack
  initiation approach which could be utilized to predict/estimate the servi
 ce life of components subjected to fretting fatigue.  \n\nBONDED PATCH REP
 AIR: Cracking is a common failure mode in structural components. Their eff
 icient and reliable repair before their complete failure is needed. This r
 esearch focused on the characterization of adhesively bonded composite pat
 ch to repair a cracked structural component along with development of fini
 te element based simple method to predict the fatigue life.\n\nCERAMICS MA
 TRIX COMPOSITES: This research focused on characterization of fatigue life
  of ceramics matrix composites under combustion and related environments a
 t elevated temperature (700 ~ 1200 deg C). These materials are needed for 
 several elevated temperature applications.\n\nNANOCOMPOSITES: This part of
  presentation will present our research effort on characterization of nano
 -composites using nano-indentation and atomic force microscopy. \n
