Armanj Hasanyan

Postdoctoral researcher

armanj@caltech.edu

Armanj Hasanyan joined the Space Structure Lab in 2018. His focus is on failure analysis of ultra-thin composite space structures. He is currently working on determining the types of failure modes present in ultra-thin structures, as well as modeling them using numerical and micromechanics approaches. His current research interests include manufacturing of ultra-thin composites, finite element simulation, micromechanics, and multiscale modeling.

Armanj completed his Ph.D. and M.S. from the University of Michigan, Department of Aerospace Engineering in 2018 and 2014, respectively, and his B.E. from Virginia Tech, Department of Engineering Science and Mechanics in 2013. His doctorate research involved developing a geometric and material nonlinear micropolar continuum theory for application towards composite structures, such as honeycomb structures, textiles, and fiber reinforced composites. Micropolar theory was applied to model localization phenomenon, such as fiber kinking in fiber reinforced composites, at the continuum scale. Some of his research interests also include topics such as nonlinear finite elements, nonlinear continuum mechanics, plasticity theory, smart materials, and plate and shell theory.
