Exfoliation Corrosion and Pitting Corrosion and Their Role in Fatigue Predictive Modeling: State‐of‐the‐Art Review

open access: yesInternational Journal of Aerospace Engineering, Volume 2012, Issue 1, 2012., 2012
Intergranular attack (IG) and exfoliation corrosion (EC) have a detrimental impact on the structural integrity of aircraft structures of all types. Understanding the mechanisms and methods for dealing with these processes and with corrosion in general has been and is critical to the safety of critical components of aircraft.

Incidence of Difficult Facemask Ventilation and Intubation in Patients Undergoing Cardiac Surgery—A Cross‐Sectional Observational Study

open access: yesHealth Science Reports, Volume 9, Issue 3, March 2026.
ABSTRACT Background and Aims Cardiac surgery patients often present challenging airways and limited cardiopulmonary reserves, necessitating meticulous preoperative assessment by the anesthesia team. This observational study aimed to determine the incidence of difficult airways in cardiac surgery patients and identify predictive factors. By addressing a

Effects of Strain Rates on Kinetics of Elements of Repeated Pattern Structures: A Continuous Modeling Approach

open access: yesShock and Vibration, Volume 19, Issue 4, Page 545-554, 2012., 2012
Space inflatable technology is a promising solution to placing large metrology systems in space. Lighter weight, higher packaging efficiency, and easier maintenance are among a few of their advantages over mechanically deployed structures. On the other hand, their large volume after deployment makes them susceptible to disturbances in space. Therefore,

Characterization and Reporting Protocols for Structural Power Composites: A Perspective

open access: yesAdvanced Energy Materials, Volume 15, Issue 42, November 11, 2025.
Here, the issues for testing and reporting on structural power composites are described: multifunctional materials that can carry loads while providing electrical energy. As well as proposing best practice, the development of a “universal coupon” is recommended for studying these materials and any interactions that occur between the two functions ...

Dynamic Effects of Embedded Macro‐Fiber Composite Actuators on Ultra‐Light Flexible Structures of Repeated Pattern‐ a Homogenization Approach

open access: yesShock and Vibration, Volume 19, Issue 1, Page 81-100, 2012., 2012
Motivated by deployable satellite technology, this article presents a homogenization model of an inflatable, rigidized lattice structure with distributed macro‐fiber composite (MFC) actuation. The model is based upon a general expression for the strain and kinetic energy of a fundamental repeated element of the structure.

An Iterative Determination Method of an Axial Deployment Force of a Lanyard‐Deployed Coilable Mast in Local Coil Mode

open access: yesInternational Journal of Aerospace Engineering, Volume 2024, Issue 1, 2024.
The axial deployment force is an indispensable parameter of a lanyard‐deployed coilable mast, which reflects its load capacity in practical applications. However, research on the axial deployment force in the literature is very limited, and there are no mature numerical methods to determine this parameter in the design stage of coilable masts.

Experimental Measurement of Picometer Scale Spontaneous Vibrations in a Precision Deployable Boom under Thermal Loading

open access: yesShock and Vibration, Volume 14, Issue 2, Page 133-149, 2007., 2007
This paper reports observations and analysis of picometer scale spontaneous vibrations in a precision deployable boom under thermal loading. The structural test article is a deployable boom previously flown in space. It exhibited spontaneous vibrations during the temperature rise following a night to day transition on orbit.

Shape Adjustment of a Large Planar Phased Array Antenna With Nonlinear Cable Actuators

open access: yesInternational Journal of Aerospace Engineering, Volume 2024, Issue 1, 2024.
Shape adjustment of large planar phased array antennas is significant because the shape distortion of phased arrays can greatly reduce the antenna’s gain in the observing direction. This study selects the inherent diagonal cables driven by motors as actuators, initially used to improve the stiffness of the antenna structure. The shape adjustment can be
