Material Tests and Mesoscale Computer Model for Ballistic Impact on Carbon Fiber Composite
EPJ Web of Conferences, 2018 Two-dimensional (unidirectional) and 3-D woven carbon fiber reinforced plastic (CFRP) panels were produced by Albany Engineered Composites. Coupons were machined from the laminates for various mechanical tests in tension, torsion, and delamination.

Ballistic and numerical simulation of impacting goods on conveyor belt rubber
Polymer Testing, 2015 Impact loading is an important process in the transport industry as it causes wear and failure of critical components. Conveyor belts are of particular importance as they are used in practically every industry where large quantities of goods are moved over short (<10 m) or long distances (>1 km).

Molecular Friction Trumps Viscosity in Angstrofluidic Transport
Small, EarlyView.Single‐file transport through sub‐1 nm graphene nanopore and carbon nanotube is investigated using molecular dynamics and ergodic trajectory sampling. The study shows that confinement geometry and wall‐fluid interaction strength govern molecular mobility, allowing atomistic motion to be translated into a continuum‐based resistance coefficient for ...

steel research international, EarlyView.The high‐strain‐rate behavior of resistance spot‐welded DP800–DP1000 joints is investigated. Results show that microstructural gradients across BM–HAZ–FZ govern hardness, strain rate sensitivity, and failure modes. While strength increases with strain rate, energy absorption is controlled by ductility, with DP800–DP800 joints showing superior ...

Experimental verification of numerical simulation of projectile impact on ballistic shields
Archive of Mechanical Engineering, 2013 Abstract In this work, the author presents experimental verification of numerical simulation of projectile impact on constructional shields. The experimental tests were performed at a unified test stand to investigate ballistic resistance of materials in field conditions.

Tetragonal distortion of the multiferroic compound α‐LiFe5O8 from first‐principles calculations
Journal of Applied Crystallography, EarlyView.First‐principles calculations suggest the tetragonal space group P43212 for the multiferroic compound α‐LiFe5O8, with a direct band gap smaller than that in its widely known cubic space group P4332. The tetragonal lattice distortion a > c is explained by relatively strong antiferromagnetic exchange interactions parallel to the c axis and by Fe–O–Fe ...

Journal of Forensic Sciences, EarlyView.Abstract Sharp force trauma has been the leading cause of homicide in England and Wales for more than a decade. Experimental research on sharp force trauma frequently relies on animal bone as a substitute for human remains, yet their ethical acceptability and comparability to human bone remain contested.

Modeling and Simulation of Ballistic Impact
, 2016 Numerical simulations are increasingly becoming an important tool to obtain efficient designs of protective structures, and the existing literature shows that many phenomena can be accurately described by standard methods and models. This thesis, specifically, focuses on novel methods of modeling and simulating ballistic impact.

Journal of Forensic Sciences, EarlyView.Abstract Although soft tissue simulants are widely used in ballistic research, glycerine soap is the only material that offers a clear view of the temporary cavity of a wound channel without the use of optical apparatus. However, the latter still shows some inconvenience mostly on its weight and its dehydration process when cut, making it challenging ...
