“…The essence of the above method is to remove redundant mass by optimizing the structure topology and size. Nowadays, however, a load-bearing mechanical structure is often required to possess additional attributes, e.g., energy absorption, sound attenuation, heat/mass transfer, energy storage, and so on [ 6 , 7 , 8 , 9 ]. Design and construction of lightweight multifunctional structures have thus become a focal point in a wide range of applications.…”

Ultralight sandwich constructions with corrugated channel cores (i.e., periodic fluid-through wavy passages) are envisioned to possess multifunctional attributes: simultaneous load-carrying and heat dissipation via active cooling. Titanium alloy (Ti-6Al-4V) corrugated-channel-cored sandwich panels (3CSPs) with thin face sheets and core webs were fabricated via the technique of selective laser melting (SLM) for enhanced shear resistance relative to other fabrication processes such as vacuum brazing. Four-point bending responses of as-fabricated 3CSP specimens, including bending resistance and initial collapse modes, were experimentally measured. The bending characteristics of the 3CSP structure were further explored using a combined approach of analytical modeling and numerical simulation based on the method of finite elements (FE). Both the analytical and numerical predictions were validated against experimental measurements. Collapse mechanism maps of the 3CSP structure were subsequently constructed using the analytical model, with four collapse modes considered (face-sheet yielding, face-sheet buckling, core yielding, and core buckling), which were used to evaluate how its structural geometry affects its collapse initiation mode.

As the most widely used power battery for pure electric vehicles, lithium-ion battery has been studied in detail, including electrochemical performance and mechanical safety. This paper focuses on the mechanical response and thermal runaway phenomena caused by external mechanical stress of lithium-ion batteries at different states of charge (SOC). The results show that the SOC affects the mechanical strength as well as the temperature of the battery under external stress. When stress is applied to the cell, the higher the SOC of the cell, the higher its stiffness and surface temperature. The force is determined to propagate layer by layer based on the dynamic analysis approach of stress propagation theory. The velocity is inversely proportional to the stress propagation distance. Excessive impact velocity will lead to concentration of stress in the battery, which will lead to short circuit and thermal runaway phenomenon of the battery. The findings of these phenomena are of guiding significance to the safety study of electric vehicle lithium-ion batteries.
