“…[17] Consequently, there is an urgent need for the development of a novel lightweight sandwich structure capable of maintaining mechanical properties in hightemperature environments while exhibiting elastic deformation capabilities and excellent temperature insulation properties. [18,19] EMWM elastomers, incorporating complex environmental materials such as stainless steel, have found extensive application in high-temperature and high-pressure environments. Zhang et al [20] proposed a kind of nonlinear mechanical metamaterial with increased energy absorption and tuning under quasi-static, vibration and impact loads by combining EMWM and tension structures.…”

As a novel lightweight composite structure with notable mechanical resistance and thermal insulation characteristics in high‐temperature environments, the sandwich cylindrical shell with entangled metallic wire mesh (SCS‐EMWM) has been growing interest in industrial applications. This study focuses on investigating the thermo‐mechanical behavior of the SCS‐EMWM in high‐temperature environments. The static mechanical properties of entangled metal wire mesh (EMWM) are first characterized, and the macroscopic mechanical properties are identified using the Ogden–Mullins model. Subsequently, the deformation modes at different densities and temperatures are analyzed through theoretical and finite element methods. The radial compression test of SCS‐EMWM is performed to characterize its energy dissipation (ΔW), loss factor (η), and secant stiffness (K). The quasi‐static loading‐unloading results of the EMWM reveal a positive correlation between temperature, density, and the mechanical behavior. In addition, as the density and temperature increase, the peak load of SCS‐EMWM continuously increases from 20 to 200 N. Under high‐temperature conditions, the radial compression test of SCS‐EMWM reveals a significant concurrence between experimental and simulation results regarding load variations. Furthermore, in comparison to EMWM, the loss factor of SCS‐EMWM exhibits an approximate increase of 0.1 and shows a positive correlation with temperature, while it decreases with increasing density.

“…Through the bending process instead of SPF, a more flexible shape can be achieved. Although previous studies adopted a bending process with DB to manufacture titanium alloys such as Ti22Al25Nb, each process was applied sequentially [33][34][35]. Although using SPF to generate pressure has several advantages, building equipment using this method is difficult, and forming specific shapes requires additional processes.…”

A one-step hybrid bending/diffusion bonding process (HB/DBP) was developed for application to Ti-6Al-4V sheets to effectively improve buy-to-fly (BTF) ratio of aircraft parts, integrating sequential diffusion bonding followed by a bending process. The resulting bonding characteristics of these titanium alloy sheets were analyzed. Microstructural analysis and mechanical lap shear tests were performed to estimate the bonding quality. Additionally, bonding ratio, thickness strain, and shear strength were evaluated in relation to pressure under increasing temperature. When the applied pressure was lower than 0.5 MPa, early failure occurred at the joint of the specimens. However, when high pressure was applied, early failure occurred near the joint. To discuss the phenomenon, time-dependent viscoplastic material properties were characterized, and a numerical simulation analysis was performed. Viscoplastic deformation was observed around the bending area, which caused weakness around the bond under high-pressure conditions. A prototype of a Y-shaped heat shield was manufactured and the buy-to-fly ratio was effectively improved using the newly developed process. This study demonstrates the potential of applying the developed process for producing aircraft parts and the importance of viscoplastic behavior for the analysis of final product reliability.
