Journal Articles
Experimental and computational investigations of the potential improvement in helmet blast-protection through the use of a polyurea-based external coating
Available to Purchase
Multidiscipline Modeling in Materials and Structures (2016) 12 (1): 33–72.
Published: 13 June 2016
.... Design/methodology/approach – In the present work, an augmentation of the ACH for improved blast protection is considered. This augmentation includes the use of a polyurea (a nano-segregated elastomeric copolymer) based ACH external coating. To demonstrate the efficacy of this approach, blast...
Journal Articles
All-atom molecular-level computational simulations of planar longitudinal shockwave interactions with polyurea, soda-lime glass and polyurea/glass interfaces
Available to Purchase
Multidiscipline Modeling in Materials and Structures (2014) 10 (4): 474–510.
Published: 04 November 2014
...Mica Grujicic; Ramin Yavari; Jennifer Snipes; S. Ramaswami; Roshdy Barsoum Purpose – The purpose of this paper is to study the mechanical response of polyurea, soda-lime glass (glass, for short), polyurea/glass/polyurea and glass/polyurea/glass sandwich structures under dynamic-loading conditions...
Journal Articles
Molecular- and domain-level microstructure-dependent material model for nano-segregated polyurea
Available to Purchase
Multidiscipline Modeling in Materials and Structures (2013) 9 (4): 548–578.
Published: 18 November 2013
...Mica Grujicic; Jennifer Snipes; Subrahmanian Ramaswami; Rohan Galgalikar; James Runt; James Tarter Purpose – Polyurea is an elastomeric two-phase co-polymer consisting of nanometer-sized discrete hard (i.e. high glass transition temperature) domains distributed randomly within a soft (i.e. low...
Journal Articles
Computational investigation of shock‐mitigation efficacy of polyurea when used in a combat helmet: A core sample analysis
Available to Purchase
Multidiscipline Modeling in Materials and Structures (2012) 8 (3): 297–331.
Published: 28 September 2012
...M. Grujicic; A. Arakere; B. Pandurangan; A. Grujicic; A. Littlestone; R. Barsoum Purpose Polyurea falls into a category of elastomeric co‐polymers in which, due to the presence of strong hydrogen bonding, the microstructure is of a heterogeneous nature and consists of a compliant/soft matrix...
