Effect of Different Surface Treatments on Resistance to Abrasive Wear of AISI 4140 Steel

steel research international, EarlyView.
This study investigates how different surface treatments affect resistance to abrasive wear of AISI 4140 Steel. The wear rate was significantly higher in samples subjected to conventional treatments than in samples coated using the HVOF process, demonstrating the superior efficiency of coatings applied by thermal spraying in mitigating abrasive wear ...

Recent Advances in Oriented Hydrogels: From Fundamental Mechanisms to Future Challenges

SusMat, EarlyView.
Traditional hydrogels suffer from weak mechanical properties and limited functionality due to their random polymer networks. This review comprehensively summarizes the reinforcement mechanisms of oriented structure for hydrogels, the design/fabrication strategies, and the latest application progress of high‐strength oriented hydrogels.

The Reflexive Turn in Systems Engineering: A Disciplinary Response to Complexity

Systems Engineering, EarlyView.
ABSTRACT The Future of Systems Engineering (FuSE) programme has called for the discipline to evolve as a transdiscipline capable of engaging complex eco‐socio‐technical challenges. Yet the pace of that evolution has been slower than the arguments for it would predict. This article examines why.

A comparison of the behind armour blunt trauma effects between ceramic faced and soft body armours caused by ballistic impact [PDF]

, 2002
Recently published research has characterised the behind armour blunt trauma (BABT) effects associated with high velocity ballistic impact on textile-based armour faced with a ceramic plate. Subsequently dynamic displacements, accelerations and pressures

What Is the Return on Investment of Digital Engineering for Complex Systems Development Schedules? Findings From a Mixed‐Methods Case Study on the Post‐Production Design Change Processes of Navy Assets

Systems Engineering, EarlyView.
ABSTRACT Complex engineered systems routinely face schedule and cost overruns, along with poor post‐deployment performance. Both INCOSE and the U.S. Department of Defense (DoD) have championed Digital Engineering (DE) as a potential remedy, yet most of DE's purported benefits remain anecdotal, and its return on investment (ROI) remains poorly ...

Dynamic mechanical response and failure behaviour of AlMgB14-based ceramic: experimental observation, constitutive modelling and ballistic performance evaluation

Journal of Materials Research and Technology
AlMgB14-based ceramics have emerged as promising materials for ballistic protection due to their ultra-hardness and low density. However, their dynamic mechanical behaviour and ballistic performance remain underexplored.

Prognostic Value of Initial CT Imaging for Surgical Planning and Outcomes in Panfacial Fractures: A Systematic Review and Meta‐Analysis

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objective To evaluate the reported prognostic value of initial computed tomography (CT) imaging for surgical planning and postoperative outcomes in panfacial fractures, and to determine whether CT‐derived variables have been consistently linked to clinically relevant outcomes.

Determination of the one‐electron reduced Wigner function for a molecular crystal

Acta Crystallographica Section A, EarlyView.
The first reconstruction of an experimental one‐particle reduced Wigner function for electrons in molecular crystals is reported. It relies on an ensemble N‐representable model jointly refined from the X‐ray diffraction and Compton scattering data.The Wigner function provides a complete phase‐space representation of a quantum state.

3D‐printed wound channels

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 ...
