Dr. Sagar M Doshi
Dr. Sagar M. Doshi. Dr. Doshi completed his Ph.D. defense in spring 2020 in the Department of Mechanical Engineering and the Center for Composite Materials at the University of Delaware. His research focuses on processing and characterization of nanomaterial-based hierarchical composites. Doshi has collaborated extensively with researchers from Civil Engineering, Biomechanics and Electrical Engineering to develop novel solutions for structural health monitoring of civil infrastructure and low-cost wearable sensors for human motion analysis and has been cited numerous times (Google Scholar: >207 citations, h-index: 6, i10-Index: 5).
Happy Holidays from MCET
As we prepare for our next steps regarding exciting opportunities and challenges in grants, testing opportunities, and company growth 2023, MCET would like to thank all those who helped us in 2022.
FRP Pipeline Repair SHM Solutions
Metal structural pipeline components and other infrastructure deteriorate over their service life due to static and cyclic loading, exposure to corrosive chemicals, and harsh environments. The result is progressive weakening of the structural
elements due to corrosion, section loss and cracking. All structures exposed to cyclic loading are susceptible to deterioration, and incidents at oil and gas pipelines in the United States resulted in 339.72 million U.S. dollars of reported total costs in 2020.
Detect the Structural Crack or Strain- in Real Time
Metal, concrete, and composite structures exposed to cyclic loading, corrosion, and abuse, are susceptible to fatigue cracking, strain, and ultimately, structural failure. As a result, monitoring this critical infrastructure is of vital importance before the damage reaches a critical stage and the structure fails.

Using piezoresistance to monitor fatigue in metal structures
Metal structures exposed to cyclic loading, including aerospace structures, bridges, and vibrating machinery, are susceptible to fatigue cracking. Monitoring fatigue cracks in metal structures is thus critically important for preventing failure by making repair decisions before a crack reaches its critical length, leading to fracture.

CNT Monitoring & Repair- Infrastructure
Metal structural components of aircraft, machines, vehicles, and infrastructure deteriorate over their service life due to static and cyclic loading, exposure to corrosive chemicals, and harsh environments. For example, steel bridges are particularly susceptible to fatigue cracking as increased traffic demands often exceed their design load capabilities and members often have fatigue-sensitive details. Corrosion due to deicing chemicals can also result in deterioration and reduction in load-carrying capacity. The result is progressive weakening of the structural elements due to section loss and cracking.
Pipeline damage detectable through continuous piezoresistive sensors
The average yearly costs of US pipeline incidents increased to approximately $733M/yr from the period of 2016-20, an increase over the previous five years. These hazards represent significant costs in terms of personal injury (2,000-4,000 injuries/yr in the US Oil & Gas industry), environmental damage, and monetary losses due to fines, cleanups, and system shutdowns that can approach $1M/day.
