How Do Thermal Recovery Methods Affect Wettability Alteration?

open access: yesJournal of Petroleum Engineering, Volume 2014, Issue 1, 2014., 2014
We will investigate the effect of temperature on wettability. First, we will list and summarize the different schools of thoughts from previous literature describing wettability changes for sandstone and carbonate reservoirs at elevated temperature. Next, we will describe the properties that affect wettability: how they alter wettability and how they ...

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.

Axial Vibration Characteristics of Piecewise Large Space Truss Structures

open access: yesInternational Journal of Aerospace Engineering, Volume 2026, Issue 1, 2026.
Large space truss structures (LSTS) are essential load‐bearing components in many spacecraft. Owing to their large size, lightweight design, and high flexibility, they inherently exhibit very low natural frequencies and small damping ratios, making them susceptible to persistent vibrations induced by small disturbances.

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.
