Journal ArticleDOI
High speed synchrotron x-ray phase contrast imaging of dynamic material response to split Hopkinson bar loading
Matthew Hudspeth,Benjamin Claus,Steven Joshua Dubelman,John T. Black,Alex B. Mondal,Niranjan D. Parab,C. Funnell,F. Hai,M. L. Qi,Kamel Fezzaa,S. N. Luo,Weinong Chen +11 more
TL;DR: Synchrotron x-ray phase contrast imaging of material systems being loaded with the Kolsky bar apparatus demonstratively depicts the effectiveness of the novel union between these two powerful techniques, thereby allowing for in situ analysis of the interior of the material system during high-rate loading for a variety of applications.
Journal ArticleDOI
Experimental assessment of fracture of individual sand particles at different loading rates
Niranjan D. Parab,Benjamin Claus,Matthew Hudspeth,John T. Black,Alex B. Mondal,Jianzhuo Sun,Kemal Fezzaa,Xianghui Xiao,Sheng-Nian Luo,Wayne Chen +9 more
TL;DR: In this paper, a modified Kolsky bar setup was used to apply controlled dynamic compression on two contacting sand particles, and 3D X-ray tomography is used to assess the failure of sand particles under static compressive loading.
Journal ArticleDOI
Dynamic failure of Dyneema SK76 single fibers under biaxial shear/tension
TL;DR: In this paper, a video-based torque sensing technique was used to determine the residual tensile strength of single fibers when subjected to a specific grade of shear stress and longitudinal surface striation development.
Journal ArticleDOI
High speed X-ray phase contrast imaging of energetic composites under dynamic compression
Niranjan D. Parab,Zane A. Roberts,Michael Harr,Jesus O. Mares,Alex D. Casey,I. Emre Gunduz,Matthew Hudspeth,Benjamin Claus,Tao Sun,Kamel Fezzaa,Steven F. Son,Weinong Chen +11 more
TL;DR: In this article, high speed synchrotron X-ray experiments are conducted to visualize the in situ deformation and the fracture mechanisms in polymer bonded explosives (PBXs), which are composed of octahydro-1,3,5,7-tetranitro- 1, 3, 5,7tetrazocine (HMX) crystals and hydroxylterminated polybutadiene binder doped with iron (III) oxide.
Journal ArticleDOI
Strain rate-dependent tensile properties and dynamic electromechanical response of carbon nanotube fibers
Amanda S. Wu,Xu Nie,Matthew Hudspeth,Weinong Chen,Tsu-Wei Chou,David S. Lashmore,Mark Schauer,Erick Tolle,Jeff Rioux +8 more
TL;DR: This first look into the dynamic tensile behavior of CNT fibers demonstrates their potential to serve as sensors in high rate applications and real-time electrical measurements provide correlations between high rate deformation/damage mechanical behavior and electrical resistance of the fiber specimens.
