Sameer Jape

Postdoctoral Researcher-Mechanical Engineering

| 303-275-3847

Sameer joined NREL’s Thermal Sciences Group in April 2019. His research includes finite element modeling and analysis of thermomechanical stresses, fatigue and failure, and creep response of high-temperature nickel-based superalloy components used in receiver structures for concentrating solar power applications. Before joining NREL, Sameer worked as a postdoctoral researcher at Texas A&M University where he conducted research on the design, fabrication, and structural and electromagnetic analysis of smart material-based morphing origami antennas. His doctoral work at Texas A&M included the computational modeling of thermomechanical material response and fracture under thermal and mechanical loading of shape memory alloy smart materials.
