Considering the interaction between fiber-inclusion and strong constraining interphase, forth-phase model is suggested to determine the local stress field distribution of three-phase element in eutectic ceramic rod. On the basis of the volumetric average strain, the effective compliance tensor increment of eutectic ceramic rod is obtained. The remote stress boundary condition of the eutectic ceramic rod is accounted for getting the micro stress field of fibers in eutectic ceramic rod. The results show the micro stress field of the fiber-inclusion in eutectic ceramic rod is associated with the

Abstract: The functional properties of shape memory alloys (SMAs) may be affected by the material size and thus is important for designing micron-sized devices. Here the diameter-dependent size effect was demonstrated in Ni-Mn-Ga fibers with diameters of 15, 41, 53 and 70μm. The effect of fiber diameter on the shape memory effect (SME) and superelasticity (SE) was systematically studied. The results showed that all Ni-Mn-Ga fibers exhibited good stress assisted thermal cycles and SE, both diameter-dependent. For stress assisted thermal cycles, the temperature hysteresis of martensite transform

Usage of discontinuous glass fibers in injection- and compression-molded resin components is rapidly increasing to improve their mechanical properties. Since added fiber contributes to more strength along the fiber direction compared with transverse direction, the mechanical properties of such components strongly depend on the fiber orientation. Therefore, it is important to estimate the fiber orientation distribution in such materials. In this article, we are presenting a recently developed method to estimate fiber orientation using micro computerized tomography (CT) scan-generated three-dime

Such plastics span a continuum of sizes, encompassing large (macro-), medium (micro-, typically defined as particles between 1 μm and 5 mm), and smaller (nano-) plastics. All are of environmental relevance. Particle sizes are dynamic. Large plastics may fragment over time, while smaller particles may agglomerate in the field. The diverse morphologies (fragment, fiber, sphere) and chemical compositions of microplastics further complicate their characterization. Fibers are of grow

Temperature is one of the seven base units of the physical world, and the temperature sensors have wide applications in the lives, research, and industries. This chapter presents a brief introduction on four classic types of temperature sensors, including thermometers, thermocouples, resistance temperature detectors (RTD), and thermistors. These traditional temperature sensors have some limitations and are not suitable for dynamic measurements. To meet the demand for temperature measurement under various extreme and complex conditions, four advanced types of temperature sensors are introduced.

Abstract The microstructure of typical carbon fiber reinforced polymer composite (FRPC) materials is composed of 6 μm diameter fibers, embedded in polymer resin. Because the fibers are the main load bearing constituents, the mechanical performance of the overall laminate is inherently linked to the nanostructure of individual fibers. In-situ characterization of individual fiber properties at the micro and nano-scales poses challenges due to the small size-scales associated with testing. In addition, the complex nanostructure of typical PAN-based carbon fibers, which is composed of folded graph
