Academic Projects

M. Tech. Projects

Neural Network Modeling of stability analysis of Glass-Fiber Reinforced Composite Plates (Funded by Institution of Engineers, India-Kolkata, India)

  • Objective: To assess the stability of glass fiber reinforced composite using varied volume fraction and aspect ratio of plates
  • The fiber reinforced plates were manufactured using vacuum bagging techniques were fiber to matrix were varied.
  • Benchmarking experiments are done to validate the measure the stability, out of plane displacement, morphological studies to check the failure pattern and estimation of volume fraction as per ASTM–D 2584.
  • The experiments were carried out as per Compression after Impact standard. Optimum Volume fraction was found were we could predict the maximum load at which the plate failed.

Mathematical Modelling

  • Developed mathematical model based on neural network modeling were datas obtained during experiment were validated with predicted values.
  • Development of different training networks and prediction of values with experimental values.

B. Tech. Projects

Design and Development of Automatic Headlight Dimmer Unit for Automobiles

  • Objective: To design a microcontroller unit along with a light sensor for automatic dimming of Headlights
  • To sense the intensity of incoming light, condition that the light beam is high or low and  transfer the signal to microcontroller unit.
  • The sensor was able to sense the light at an optimum distance and give the command to the controller in order that the headlight was dipped based on whether incoming light was at high beam or low beam.

Areas of Interest

  • Experimental Mechanics of Materials, Non Linear Mechanics
  • Composite Materials Processing and Structural applications.
  • Mechanical behavior of Materials, Structural Health Monitoring.
