Crash Behavior of DP800–DP1000 Advanced High‐Strength Steel’s Dissimilar Resistance Spot Welded Joints Under Quasi‐static and High Strain Rates

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 ...

How many shots are enough? Optimizing precision measurements when testing lead‐free ammunition

Wildlife Biology, EarlyView.
Growing concern about lead exposure in scavenging wildlife and the consumers of game meat has increased interest in evaluating the performance of lead‐free rifle ammunition. Testing both accuracy and precision helps ensure reliable shot placement while reducing the risk of non‐fatal woundings.

Sharp force trauma analysis without animal bones: A proposal for sustainable and ethical bone proxies

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.

The impact of the coupling relationship between projectile size and yarn dimension on the ballistic performance of plain weave fabric

Defence Technology
Aramid fibers, due to their relatively high inter-yarn friction, high strength, high modulus, and other characteristics, have become a typical representative of flexible anti-ballistic materials in modern warfare. Current research on the anti-penetration

Adaptive Optical Layers: Efficient Tall Cell Grids for Liquid Simulation

Computer Graphics Forum, EarlyView.
Abstract Tall cell grids have been proposed as an efficient approach to accelerate large‐scale liquid simulation. In this framework, regions near the liquid surface are discretized with regular grids, while regions farther away are represented by elongated rectangular cells.
