“…This difference between the angles measured numerically and experimentally could be explained due to the resolution of the photoelastic technique and/or a low stiffness response of the matrix in the numerical model. It is noted that debonded areas and non‐rigid bonding may influence the mechanical response; however, an in‐depth analysis of the effect of the interface bonding on the response is beyond the scope of this study. It can also be seen that the magnitude of σ 1 is larger in the zone near the area where the fiber enters the matrix block and decreases towards the embedded fiber end.…”

“…It is noted that in the simulation, the computed maximum shear stresses are overestimated when compared to those calculated in the experimental work , which could be explained by the perfectly bonded rigid interface. A simulation that takes into account a cohesive interface could provide more accurate results; however, since we are interested in using the numerical simulations to better understand the 3D stress distribution and directions, the model here employed was deemed sufficient for our simulation results.…”

Photoelastic and numerical analyses of the stress distribution around a fiber in a pull‐out test for a thermoplastic fiber/epoxy resin composite

The stress distribution in a polyester fiber/epoxy matrix model composite subjected to pull‐out test was investigated through photoelasticity and elastic‐plastic numerical analysis using finite element (FE) simulations. A photoelastic technique was used to obtain isoclinic fringe patterns, which were employed to construct a pair of orthogonal families of principal stress trajectories for a pull‐out specimen. It was found that the trajectories of the maximum principal stress tend to converge at points where either the maximum interfacial shear stress is located or there is stress concentration. The FE simulations proved to be a powerful tool that allowed understanding the 3D stress distributions, in areas located near the embedded fiber, where principal directions were influenced by radial stresses, effects of Poisson's ratio, reduction of fiber diameter and plasticity. The FE simulations could be extended to quantify stress fields in other single‐fiber test configurations. POLYM. COMPOS., 39:E2397–E2406, 2018. © 2017 Society of Plastics Engineers

“…An equation of the characteristic length on the stress contour and the interfacial strength was derived [59]. A stress transfer behavior has been investigated by Budiman et al [60]. The evaluating techniques of the interfacial properties using single fiber surrounding matrix indicate that the distance between fibers should be as close as possible yet no contact should be maintained.…”

The main challenging issues of vehicles with electric propulsion are on the limited energy source due to relatively low battery capacity and low excitation of power traction. They can be tackled down by designing lightweight structures for frameworks and bodies of the vehicles. Composite materials which have a high strength to weight ratio are the best choice for designing and manufacturing the lightweight structures. A review of recent progress in utilization of the composite materials for electric vehicle structures is presented. It focuses on how the structures can support the electric vehicles to compete with internal combustion engine vehicles regarding their performance on the road. The utilization of composite material for structures of railway vehicles is also summarized. Furthermore, discussions are extended to the key technologies required for applying the composite materials in Indonesia such as composite-metal joint technology, fiber and matrix production technology, and numerical analysis competency for modeling the composite.

“…To ensure that no delamination occurs in a commercial product, it is very important for the manufacturer to create strong interface bonding. Therefore, it is critical to measure and quantify the interfacial strength of multilayer thin-film products correctly and accurately (Chen et al, 2013;Budiman et al, 2017;Takahashi et al, 2016).…”

Multilayer thin films polymer have been commonly used in a wide range of electronics applications, such as solar cells, photoconductors, semiconductors, and light-emitting diodes, in which failure due to delamination can occur. For evaluating and improving the quality of a multilayer thin-film product, the interfacial strength between its layers must be measured correctly and accurately. In this work, the interfacial strength of a multilayer thin-film polymer was quantified by measuring the interfacial energy release rate (interfacial fracture toughness), Gi, using the nanoindentation test technique. Three specimens of four-layer thin films were fabricated on a glass substrate. The top layer of each specimen was prepared with different thicknesses. The unloading curve technique introduced by Kozuki and Kishimoto (2010) was implemented to quantify the Gi of each specimen. Then, crosssectional observation of the specimens was performed to confirm the layer thicknesses and to identify the delamination condition after the test. The measured Gi tended to increase as the range between the two unloading curves used to calculate the delamination energy widened. This phenomenon is believed to be caused by the plastic energy of the deformed films during the indentation process. Finally, an empirical method for eliminating the effect of the plastic energy on the measured Gi was proposed. Using this method, a pure Gi value can be effectively extracted; thus, the interfacial strength of multilayer thin-film polymers can be measured correctly and accurately.
