Graduate Students

Geeta Monpara (PhD)Geeta Monpara (PhD), Email: gmonpara@uwyo.edu

Geeta is originally from India. She completed her Bachelors and Masters degrees in Metallurgical Engineering and Materials Science from Indian Institute of Technology Bombay. She joined the group in Summer 2014 as a PhD student. Her research work is focused on developing methodologies to couple crystal plasticity, irradiation damage, and fracture/cohesive failure modeling in the MOOSE framework. The modeling tools that she is developing will be used to better predict performance of nuclear cladding materials.

Faisal Bhuiyan (PhD)Faisal Bhuiyan (PhD), Email: faisalhbhuiyan@gmail.com

Faisal is from Chittagong, Bangladesh. He has a B.Sc. in Mechanical Engineering from Bangladesh University of Engineering and Technology (BUET) and joined the group in Fall 2014. His research involved the development of a physics-based methodology for reliability prediction in composite structures. In addition to static, fatigue and creep damage prediction in composites, Faisal also spent considerable effort studying the effects of microstructure variability on the performance of composites.

David LeonhardtDavid Leonhardt (MS), Email: dleonha1@uwyo.edu
David is from Thermopolis, Wyoming. He has a B.S. in Mechanical Engineering from the University of Wyoming and joined the group in Summer 2015. His research focused on improving the fatigue life of nonlinear plate springs. His work involved parameterized finite element modeling of the plate geometry, coupled with material characterization. Both the material properties and plate geometry have a significant impact on the actuation force and fatigue life. The end result of this research was a software package enabling more robust nonlinear spring design. 

 

Hamid SaneiHamid Sanei (PhD), Email: sanei@psu.edu
Hamid is from Mashhad, Iran. He earned his bachelor s and master s degrees at Azad and Ferdowsi University of Mashhad, respectively. He started his Ph.D. at University of Wyoming in Spring 2012 and joined the group in Spring 2014. His research focused on the reliability prediction of fiber reinforced polymers. He has worked to correlate the variability in microstructures to scattering of mechanical properties at the macroscale. To that end, he created a microstructural model with multiscale defects and isolated the effect of individual defects to monitor their influence on composite structural reliability. Modeling the real rather than the ideal, and random instead of deterministic microstructures, enables simulation of random failures similar to those observed experimentally. Hamid is currently an Assistant Professor at Penn State University-Behrend College.

 

Siavash SarrafanSiavash Sarrafan (MS), Email: ssarrafa@uwyo.edu
Siavash is from Mashhad, Iran. He joined the group in Spring 2013 and graduated in Fall 2015. He has his BS and MS in Mechanical Engineering from Ferdowsi University of Mashhad. His research focused on dislocation dynamics in thin films, specifically on developing a computationally efficient 2.5D methodology for studying methods to tailor dislocation microstructures. This will lead to better understanding and control of dislocations thin films, which promises significantly enhanced mechanical, optical, and electrical properties.

 

 

Eric JensenEric Jensen (MS), Email: eric.jensen@allegion.com
Eric is from Douglas, WY and has a B.S. in Mechanical Engineering from the University of Wyoming. His research focused on the creep and fatigue behavior of fiber reinforced polymers. He extended a physics-based fatigue model to also predict creep behavior of composite laminates. In conjunction with this effort he developed an optical strain measurement system to monitor strain distributions during testing, particularly for long term creep tests. This will allow for future improvements to the creep/fatigue model and permit robust model validation. 

 

Kedar MalusareKedar Malusare (MS), Email: kedar.malusare@stutzkiengineering.com
Kedar is from Mumbai, India. He has a B.E in Mechanical Engineering from the University of Mumbai and joined the Fertig Group in Fall 2012 and graduated in the Spring of 2014. He investigated the relationship between strain energy and volume average constituent stresses. His research focused on developing computer simulations to study the variation of interaction energy for a variety of different fiber configurations, load states, and constituent properties. This will be used to augment the existing failure theories that use volume average quantities to better predict failure.
