“…HUC that circumscribed inside a circle and the critical point of intersection where the fibers placed taking positions along the edges as shown in Figure 1, the inside angles of the regular hexagonal is 60 0 . D f and s are the diameter of fibers and the radius of the circumscribed circle, respectively; (Rumayshah et al, 2021) this radius is equal to the height edge length of the circumscribed circle and the packing formula can be expressed as:…”

“…The SUC offers a symmetric geometry that simplifies the analysis of packing arrangements and allows for efficient utilization of computational modeling. The packing formula can be expressed as (Rumayshah et al, 2021) Those laminate arrangements are always balanced so that they are symmetric about the central line to assure the balance of mechanical properties; thus, buckling can be avoided. A 3D-RVE was derived from the 2D-RVE obtained using the Monte Carlo algorithm within ABAQUS CAE software by extruding the 2D-RVE in out-of-plane direction to form the 3D-RVE.…”

In this investigation, a 3D micromechanical modeling methodology based on different types of unit cell configuration and representative volume element (RVE) is used to capture the micro-macro mechanical properties of unidirectional (UD) and bidirectional (BD) fiber-reinforced synthetic resin composites. In this regard, hexagonal unit cell and square unit cell were established in order to explore the influence of packing density on representative microstructure properties, considering no effects at the interphase zone between the fiber and the matrix. The virtual geometric generation of 2D-RVE fibres inclusion model process is driven by statistical Monte Carlo simulation algorithm, which is then incorporated into FE solver to develop 3D-BDC RVE laminate model within a virtual scheme. In addition, applying the linear constraint of displacement simulation ensures that the RVE behaves as expected under uniaxial and in-plane loading conditions, leading to more accurate results. This remote constraint helps capture the realistic behaviors of the UD and BD composites models and enables the evaluation of mechanical properties, deformation patterns, and stress distributions within the presented RVE.

“…The critical contribution of this research is to identify the eff ect of damage size between faceplate and core due to free vibrations. This numerical study was performed by comparing simulation results using ABAQUS package [33], [34] with the experimental results to verify the damage case. In the fi nite element model, the sandwich material was modelled using the layer of solid or shell elements.…”

One of the most innovative developments in the field of advanced materials is sandwich materials. Sandwich material applications need standard requirements to be applied to marine structures, especially on ship construction. Sandwich material research is conducted on a laboratory scale to obtain the appropriate material composition in its development. In the process of developing this material, the material can be damaged. Most damage occurs in the core material, which results in difficulties in the identification process. This study compares damage identification methods based on free vibration analysis on the side sandwich plate of the ship’s hull. Damage-based identification is carried out to determine the response of vibration to the damage that occurs. Moreover, the method in this research uses a numerical approach and experimental vibration measurement. Numerical modelling is used to determine the appropriate boundary conditions and is shifted in experimental measurement. Damage modelling assumes that the material experiences core failure with a numerous variation model. Quantification of damage on the core correlates with natural frequency reduction due to a decrease in the stiffness of the sandwich material. Hence, the difference in the deviation value is used to determine the accuracy of damage identification.
