Modeling the Age-related Decrease in Ballistic Limit Velocity of Polycarbonate Vision Panels Using a Johnson-Cook Material Model Coupled with Variable Failure Criteria [PDF]

open access: yesJournal of Machine Engineering, 2023
Machine tools are equipped with polycarbonate vision panels that allow the operator to observe the machining process and protect him from ejected fragments. Adequate protection is demonstrated by impact tests.

Effect of Periphery Fixity on Ballistic Limit of Thin Aluminum Plate Subjected to Blunt and Ogival Projectile Impact

open access: yesInternational Journal of Applied Mechanics and Engineering, 2014
Three-dimensional numerical simulations were carried out with the ABAQUS/explicit finite element code to study the influence of target boundary conditions on its ballistic limit. 1mm thick 1100-H12 aluminum target of 255 mm span diameter was hit by 19 mm

Multiphoton Quantum Reservoirs For Robust Multidimensional Computing. [PDF]

open access: yesAdv Sci (Weinh)
Projective measurements reveal hidden multidimensional quantum networks within classical multiphoton fields, enabling robust quantum reservoirs for room‐temperature quantum simulation, prediction, and information processing. These networks transform noisy classical photonic platforms into scalable quantum computational architectures.
