This presentation summarizes a student project on monitoring pipeline bending and buckling through strain gauges. A team of 4 students led by Jamshid Khan is working under advisor Dr. Naseer Ahmad. The project aims to detect pipeline damage through strain gauges. Objectives include determining pipe lifetime, rapidly detecting damages, and reducing ruptures. The team has made 54% progress, including designing strain gauges, an amplifier, microcontroller, and conducting an ANSYS analysis on a steel pipe model. Future work involves practical experiments, a wireless system, and microcontroller programming.
