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

open access: yessteel 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 ...

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

open access: yessteel 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

open access: yesSusMat, 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.

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

open access: yesSystems 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 ...

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

open access: yesWorld 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.
