Research projects

• Prediction of Damage Growth in Large-Scale Composite Structures (Sponsor: Air Force Research Laboratory, Dayton, OH)

• Tools for Assessing the Durability And Damage Tolerance of Fastened Composite Joints (Sponsor: Air Force Research Laboratory, Dayton, OH)

  Analyze the capability of existing progressive damage analysis tools for damage prediction of composite connections with metallic bolts.

• Continuum Damage Modeling of Structural Composites Under Operating Conditions (Sponsor: Air Force Research Laboratory, Dayton, OH)

Develop methods for analytically predicting and validating the  response and life of composite structures exposed to static and  dynamic loading environments. Multiscale modeling methodology has  been used to pass the information from microstructure level to predict  the material behavior at structural scale under progressive  damage accumulation.

• Exploratory investigation on development of damage mechanics based methodologies for lifing of aeroengine components (Sponsor: Defense Metallurgical Research Laboratory, Hyderabad, India)
  

The problem addressed in this project was to estimate the damage within the aeroengine components during service condition using some intrinsic property of material. I proposed an one dimensional damage model which could be applied to all metallic materials to estimate the damage within it during service. In this model the micro scale damage is captured through macro response of a material using spring damage model. Alternating Current Potential Drop (ACPD) technique was simulated to measure the damage within the material.
