Solitonic State in Microscopic Dynamic Failures
, 2018 Onset of permanent deformation in crystalline materials under a sharp indenter tip is accompanied by nucleation and propagation of defects. By measuring the spatio-temporal strain field nearthe indenter tip during indentation tests, we demonstrate that ...

A new split Hopkinson tensile bar design
International Journal of Impact Engineering, 2012 This work presents a new design for a split Hopkinson tensile bar (SHTB) as well as generated representative experimental results. The new design uses a U shaped striker bar as projectile and addresses several shortcomings of classical SHTB designs using hollow striker bars.

The Journal of Wildlife Management, EarlyView.Antler characteristics are influenced by a combination of genetics, age, and environmental factors, notably habitat quality and resource availability. In this study, we explored how diverse environmental factors, including climate and land cover composition, affect antler size, tine configuration, and the distribution of record‐scoring white‐tailed ...

Failure Mechanisms of Short Fiber Reinforced Composite Materials Subjected to Dynamic Loading
Polymer Composites, EarlyView.Failure Mechanisms of Short Fiber Reinforced Composite Materials Subjected to Dynamic Loading. ABSTRACT The mechanical behavior of short carbon fiber reinforced polylactic acid (SCF/PLA) composites fabricated by fused deposition modeling (FDM) is crucial for engineering applications, yet their strain‐rate dependence is not fully understood.
