Study on mechanical properties of aeronautical composite material interference-fit structures in hygrothermal service

Hangkong gongcheng jinzhan
Currently，the study on the influence of hygrothermal environment on composite material is more inclined to the material composition structure，rather than the composite connection.

Impacts of Change‐Type and State‐Type System Qualities on Complex System Architectures

Systems Engineering, EarlyView.
ABSTRACT System qualities, such as scalability, expandability, and reconfigurability, are key requirements of complex systems. Requirements associated with system qualities are important factors in design trade space analyses, but systems engineering design methodologies make only limited use of these qualities, hindering a holistic understanding of ...

Architecting and Industrializing Advanced Production and Manufacturing Systems for Critical Industries

Systems Engineering, EarlyView.
ABSTRACT Advanced production systems play a vital role in modern society. Such systems are developed and industrialized over multiple years and at great expense. The complexities of these systems are exacerbated in the case of metal additive manufacturing, which involves numerous process variables and relies on various auxiliary systems.

Effect of foreign object damage on fatigue performance of Inconel 718 welded joints

Scientific Reports
Foreign object damage (FOD) in Inconel 718 base metal(BM) and welded joints(WJ) was investigated using pendulum impact testing. The effects of impact energy on damage morphology, microstructure, and fatigue performance were analyzed.

Quasi-Static Crushing Simulation Research and Failure Mode Analysis of Composite Thin-Walled C-Channel Specimen

Journal of Aeronautical Materials, 2017
To study the crushing energy-absorbing characteristics and failure mode, the multi-shells finite element model of composite thin-walled C-channel specimen was established based on the quasi-static crushing test results.

Accelerating Mission Engineering: Evidence of a Stratified Landscape and a Path Toward Unified Practice

Systems Engineering, EarlyView.
ABSTRACT Mission Engineering is maturing as a Systems Engineering discipline, yet adoption of its common frameworks remains stratified. This study examines whether selective adoption is observable across ME scholarship and develops a framework to address identified barriers.
