“…At the same time theoretical models of push-out mechanics has been developed to interpret measured push-out responses and to calibrate interface parameters [9][10][11][12][13][14][15][16]. In this study we used an instrumented macro-indentation device (< 2kN) for push-out test.…”

Brittleness problem imposes a severe restriction on the potential application of tungsten as high-temperature structural material. In this paper, a novel toughening method for tungsten is proposed based on reinforcement by tungsten wires. The underlying toughening mechanism is analogous to that of fiber-reinforced ceramic matrix composites. Strain energy is dissipated by debonding and frictional sliding at engineered fiber/matrix interfaces. To achieve maximum composite toughness fracture mechanical properties have to be optimized by interface coating.In this work, we evaluated six kinds of ZrOx-based interface coatings. Interfacial parameters such as shear strength and fracture energy were determined by means of fiber push-out tests.The parameter values of the six coatings were comparable to each other and satisfied the criterion for crack deflection. Microscopic analysis showed that debonding occurred mostly between the W filament and the ZrO x coating. Feasibility of interfacial crack deflection was also demonstrated by a three-point bending test.

“…In this section, we shall apply it to analyze the experimental tests reported by Kalton et al [5]. In their experimental work, the interfacial deformation behavior including the surface damage, debonding and frictional sliding behavior was investigated by direct SEM observation from push-out testing of titanium reinforced by SiC monofilaments.…”

“…Experimental investigations of fiber push-out in MMCs have shown that the applied load causes the fiber to debond progressively from the matrix, allowing relative sliding across the fiber/matrix interface [2,3]. The forces that cause the debonding at interface and promote frictional sliding have been observed to initially increase and then to decrease as the testing temperature increases [4,5]. The thermal residual stress during the manufacturing process further complicates the interpretation of the nonlinear decohesion and frictional behavior during the push-out process [6].…”

“…These include fragmentation, [20,21,22] pull-out, [23,24] and push-out tests. [25][26][27][28] Here, push-out tests were carried out to evaluate both debonding and frictional shear stresses, thus allowing a second objective of this work, i.e., to identify any effect of interfacial strength changes on the fatigue crack growth resistance. Analytical measurements have also been performed to identify the phases present in the interfacial zone, in particular, after elevated temperature tests.…”

Fatigue crack growth rates in a [0/90] 2s Ti-6A1-4V/SCS-6 cross-ply laminate, correlated with pushout tests, have been measured to assess the effects of varying test temperature, environment, load ratio (R), and initial stress intensity factor range (⌬K). The fatigue crack growth resistance is degraded in tests at 450°C in air, but tests carried out at test temperatures of up to 450°C under vacuum, both at R ϭ 0.1 and R ϭ 0.5, have shown crack arrest/catastrophic failure transitions (CA/CF), which are similar to those observed for specimens studied at room temperature and at 300°C in air. Moreover, for such [0/90] composites, the critical role of intact 0 deg fibers bridging in the crack wake, in promoting fatigue crack growth resistance, has been confirmed. Sudden increases of fatigue crack growth rate can be attributed to individual fiber failure(s), which were detected by acoustic emission techniques. The effect of the experimental conditions (environment, test temperature, and duration) on the mechanical behavior (fatigue crack growth rate, push-out tests, and broken fibers pull-out lengths) of this laminate may be explained by the modification of the interfacial zone (decrease in the carbon layer thickness due to oxidation and formation of TiO 2 ).
