Areas of Expertise

  • Mechanical, thermal and microstructural characterization of advanced materials
  • Experimental fracture mechanics
  • Development of FE methods to model particle reinforced composites
  • Dynamic impact (high strain rate, ballistic, drop tower) testing
  • Failure analysis of materials
  • Fabrication of nanocomposites and fiber reinforced composites

Technical Qualifications

  • Advanced Materials Characterization
    Conducted various mechanical tests such as tension, compression, fatigue to characterize mechanical properties of materials. Several thermal and microstructural tests including TGA, DSC, FT-IR, SEM were performed to characterize materials behavior. Nonlinear behavior of materials was employed in elastic-plastic model to predict the strength of fiber reinforced nanocomposites.

  • Experimental Fracture Mechanics
    Fracture toughness of nanocomposites was evaluated experimentally via several fracture tests, namely, DCB, ENF, SENT. In-situ crack propagation and fracture surfaces were investigated via SEM, optical microscope and telescope to understand the fracture mechanism.

  • Finite Element Modeling
    A fracture based micromechanical model has been used via FEM (Abaqus) to understand the failure mechanism of particle reinforced composites. Virtual Crack Closure method was used to evaluate the total strain energy release rate which was used as fracture criteria to predict the strength of particle reinforced composites. A simple 3D unit cell model was also developed to investigate the effect of particle dispersion on strength of composites.

  • Dynamic Impact Tests
    Dynamic behavior of conventional fiber reinforced composites and nanocomposites was evaluated via ballistic, high strain rate and drop tests.

  • Failure Analysis Materials
    Several experimental techniques have been used to evaluate the failure mechanisms of nanocomposite materials. Scanning electron and optical microscopes were used to investigate the failure mechanisms of cellular materials. In-situ high speed camera was used to capture the penetration event of projectile into composites which lasted for about 20-30 µsec. X-ray was used to evaluate the delaminated area of composites under drop tower test.
