Landmark Research Contribution
  • Development of a multiscale material modeling framework for solid-liquid phase change phenomena, mixing and homogenization in oxide glass, bio-implants for total hip arthoplasty, optimization of multichannel ceramic membrane for efficient hydordynamics.
  • Development of a novel method of characterizing dendritic microstructure during alloy solidification using fractal geometry.
  • Development of a novel methodology for estimating the elastic moduli of porous ceramic and metallic materials at any level of porosity based on a single ultrasonic measurement of longitudinal velocity of the green compact.
  • Development of polymer-ceramic composites for resistance against impact and fire damages.
  • Development of a QNDTE technique based on non-contact Laser Induced Ultrasonics along with an elastodynamic model of ultrasonic stress wave propagation through elastic media with a pulsed laser source. Application of this model for estimating arrival times of various primary and mode converted stress waves propagating during Laser Induced Ultrasonic (LIU) NDE in metals, ceramics and composite specimens.
