Sandwich panels’ exceptional mechanical properties and low density, owing to their multifunctional characteristics and innovative design, made them a popular choice in numerous industries. Sandwich panels with cellular cores are known for their exceptional energy absorption properties, which make them effective energy absorbers for high-impact scenarios such as accidents or explosions. For advancing research on sandwich panels, it is vital to develop innovative designs that can enhance their energy absorption and flexural stiffness. This review outlines the most essential topological parameters that influence the mechanical properties of cellular core structures. This paper gives insight into recent advancements related to optimizing sandwich panel structures for various engineering applications. The topological parameters investigated by researchers include core structure, thickness, number of layers, and material. The choice of core material governs the overall mechanical behavior of the panel. In this paper, various structures, including foam, honeycomb, lattice, corrugated, bioinspired, and various materials, are compared. Functionally graded structures were also explored in the literature as they can significantly optimize the response of sandwich panels in high and low-velocity impact applications. Similarly, a multi-layered core structure can enhance the total stiffness and specific energy absorption of the panel.

Shape memory alloys (SMAs) are smart materials that are widely used to create intelligent devices because of their high energy density, actuation strain, and biocompatibility characteristics. Given their unique properties, SMAs are found to have significant potential for implementation in many emerging applications in mobile robots, robotic hands, wearable devices, aerospace/automotive components, and biomedical devices. Here, the state–of–the–art of thermal and magnetic SMA actuators in terms of their constituent materials, form, and scaling effects are summarized, including their surface treatments and functionalities. The motion performance of various SMA architectures (wires, springs, smart soft composites, and knitted/woven actuators) is also analyzed. Based on the assessment, current challenges of SMAs that need to be addressed for their practical application are emphasized. Finally, how to advance SMAs by synergistically considering the effects of material, form, and scale is suggested.

“…The former (SME) is the ability to return to a predetermined shape upon simple heating; and the latter (SE) is the ability to recover large strains (∼8% under tension) upon unloading under isothermal conditions [3]. Due to these specific phenomena, SMA have attracted much interest for a wide range of applications, such as aerospace [4,5], medicaldental [6][7][8], automotive [9,10], civil construction [11] and others.…”

Comparisons between virtual prototyping and experimental results are notably beneficial for the development of investment casting processes. In this research, such a comparison aimed to study the castability of a Cu-Al-Mn shape memory alloy (SMA) in a modified centrifugal investment casting process that uses centrifugal force to inject the molten metal into the mold. Virtual prototyping was numerically simulated using ProCAST software applying a rectangular mesh part design. The real and virtual parts were examined for mold filling (castability), pore formation and solidification time. Using Whitlook's methodology, it was possible to validate the model created in the ProCAST software to simulate the modified investment casting process, detecting results regarding filling, solidification and porosity with a high degree of accuracy and reliability. In addition to the validation of the developed model, this work also presents estimated values for interface heat transfer coefficient (IHTC) of the metal/mold of aluminum bronze (Cu-Al and Cu-Al-Mn) alloys poured by gravity and centrifugation into plaster molds. Among the obtained values, the IHTC for the 86.7Cu-7.9Al-5.4Mn SMA were estimated at 535 W/m²K when poured by centrifugal force and 75 W/m²K by gravity. Ultimately, it was possible to verify that Cu-Al based shape memory alloy presents a high castability and a low cooling rate.
