“…The solution of FEM is not absolutely error-free as it provides approximate results for the number of discrete nodes in the solution domain. A complex problem can have infinite possible degrees of freedom (DOF), but if we discretize it, the DOF becomes finite (Zhao et al, 2023). The nodes inside the domain are interlinked to each other, and the solution of each node can help generate different functional contours.…”

Heat conduction plays a vital role in the performance and durability of any component. A wide range of applications is available which demand a good heat conduction ability. The property used to understand the heat conduction behavior in a solid is called effective thermal conductivity (Keff). It is recommended to reinforce an adequate amount of filler material in the matrix to increase the Keff of the composite. The current study used carbon black (CB) particulates, a by-product of waste tyre pyrolysis, as the reinforcing agent in the epoxy resin. The composites are prepared by solution casting method with different volume % of filler. To study the thermal behavior of samples, effective thermal conductivity, glass transition temperature (Tg), and co-efficient thermal expansion (CTE) are measured as a function of vol. % of filler. After plotting the experimental result, it is noticed that the Keff and Tg are increased, and CTE is decreased with an increase in vol. % of CB. The percolation threshold is also calculated from Keff vs. vol. % curve. Various mathematical models are incorporated to verify the experimental results of effective thermal conductivity. A finite element method (FEM) based numerical model is also developed to study the thermal conductivity behavior of composites. ANSYS MECHANICIAL APDL is used for the FEM analysis. The FEM results showed a marginal variation from experimental data at 0.9928 vol. % of CB. The reason behind this is the formation of voids during sample making, the effect of which is not taken in FEM.

“…However, the practical application of bionic multicellular structures and lattice-filled structures manufactured by 3D printing is still limited due to cost and productivity constraints. Currently, circular and square cross-sections are predominantly used in energy-absorbing TWSTs, with honeycomb [ 30 ], metal foam [ 31 , 32 ], and polymer foam [ 33 ] being the primary filling materials. In addition to solid filling materials, research has also been conducted on the crushing behavior of pressurized tubes filled with liquids and gases.…”

In the pursuit of global energy conservation and emissions reductions, utilizing beverage cans as energy-absorbing components offers potential for a sustainable economy. This study examines the impact of foam filling on the crushing behaviors and energy absorption of various types of beverage cans. Quasi-static compression tests were conducted on five geometrically sized cans filled with three densities of polyurethane foam to study their deformation modes and calculate crashworthiness parameters within the effective stroke. Results show that empty beverage cans have lower energy absorption capacities, and deformation modes become less consistent as can size increases. Higher foam density leads to increased total energy absorption, a slight reduction in the effective compression stroke, and a tendency for specific energy absorption to initially increase and then decrease. Regarding crush behavior, smaller cans transition from a diamond mode to a concertina mode, while larger cans exhibit a columnar bending mode. Next, the coupling effect of energy absorption between foam and cans was analyzed so as to reveal the design method of energy-absorbing components. The specific energy absorption of smaller cans filled with polyurethane foam is superior to that of similar empty cans. These findings provide valuable insights for selecting next-generation sustainable energy absorption structures.
