Preferentially Filled Foam Core Corrugated Steel Sandwich Structures for Improved Blast Performance

Abstract: The mechanisms by which different morphologies of preferentially foam filled corrugated panels deform under planar blast loading, transmit shock, and absorb energy are investigated experimentally and numerically for the purpose of mitigating back-face deflection (BFD). Six foam filling configurations were fabricated and subjected to shock wave loading generated by a shock tube. Shock tube experimental results obtained from high-speed photography were used to validate the numerical models. The validated numeric… Show more

“…In addition, by way of its high shear strength, it gives the structure the ability to act as a thick mono-plate. Furthermore, due to their geometry to allow airflow, the moisture retention of the structure is greatly reduced (Kazemahyazi and Zenkert, 2009; Yazıcı et al, 2015). Another most commonly used core geometry is conventional hexagonal honeycomb.…”

“…A large amount of study showed that even static, impact, or blast loading conditions, filling with foam inside the core cells improved the mechanical performance of the sandwich structures. [39][40][41][42][43][44][45][46][47][48][49][50] Not only improving strength and rigidity but also the self-healing purpose of the sandwich structure core's cells has filled with the self-healing capsules. 31 In our previous study, we have filled the Al honeycomb cells with macrocapsules carrying epoxy resin and activators as healing agents.…”

“…46 Many studies in the literature have shown that the sandwich material's static, impact, shock, and thermal properties have significantly improved without causing a significant increase in weight due to light and soft foam filling in the core cells. [47][48][49][50][51][52][53][54] Yazici et al 49 experimentally proved that sandwich blast resistance is increased by more than 50% with light and soft polyurethane (PU) foam filling. The primary mechanism of sandwich strength increase in all these foam fillings is the increase in the buckling resistance and consequently the crushing strength because the sandwich core's thin walls are supported laterally by the foam filling inside.…”
