“…4), and a good ductility of these new Fe-TiB 2 composites which is higher than that found in the literature [22,28]. Thanks to the simple shear test, permitting larger plastic strain compared to tensile tests, about γ¼50% plastic strain (corresponding to 0.5/√3 E28.9% von Mises equivalent plastic strain) may be obtained before macroscopic failure, for the hot-rolled and annealed composites, which is appreciable for forming capability.…”

“…One of the hypotheses for crack growth in particle reinforced MMCs is that K max controls the degree of particle fracture, and thus, the path of the fatigue crack [39,48]. The effect of K max on particle fracture can be seen in Fig.…”

“…Because the cumulative number of fractured particles remains constant while crack length increases, the parameter of fractured particles divided by crack length decreases while K max increases in the period following overload. Recently, Bacon et al [48] performed experiments to understand the damage mechanisms during crack propagation in 316 stainless steel metal matrix composite reinforced with 25% titanium diboride. Based on the fracture surface observation, they also observed increase in particle fracture with an increase in K max due to increase in monotonic plastic zone size.…”

a b s t r a c tMetal matrix composites (MMCs) offer high strength, high stiffness, low density, and good fatigue resistance, while maintaining cost an acceptable level. Fatigue resistance of MMCs depends on many aspects of composite microstructure. Fatigue crack growth behavior is particularly dependent on the reinforcement characteristics and matrix microstructure. The goal of this work is to obtain a fundamental understanding of fatigue crack growth behavior in SiC particle-reinforced 2080 Al alloy composites. 'In situ X-ray synchrotron tomography was performed on two samples at low (R = 0.1) and at high (R = 0.6) R-ratios. The resulting reconstructed images were used to obtain three-dimensional (3D) rendering of the particles and fatigue crack. Behaviors of the particles and crack, as well as their interaction, were analyzed and quantified. Four-dimensional (4D) visual representations were constructed to aid in the overall understanding of damage evolution.

“…Small dimensions of active micro forceps is great challenge to perform analysis and needs special environment for fatigue tests since the state of knowledge in macro technologies are not smoothly exchangeable to the micro domain [1,4]. The size effects and changed parts behavior could justify this situation of AMF in this research.…”

“…Forceps are the instruments that transmit forces from surgeon's hand to internal organs of retina of eye. Therefore, high stiffness is an important requirement for forceps [1]. Low cycle loading (LCL) of active micro forceps materials is recognized as a factor that contributes to material failure through either fractures or wear [2].…”

Antagonistic contact on tips of active micro forceps produces surface stresses leading to fracture and wear finally leading to fatal failure. It was the aim of the present research to study the outcome of low cycle loading testing parts of active micro forceps materials involving either surface contact fatigue or flexural loading mechanisms. For this purpose, this research was focused on the mechanisms of the fatigue life of 316 L-type stainless steel active micro forceps in low cycle loading conditions. This could result in the fatigue failure of active micro forceps at stress levels below the yielding stress of material. Thus, researching the material and mechanical behaviors of an active micro forceps structure and force mechanism under low cycle loading is vital. Finite element method with accurate geometry and material properties was employed for a biocompatible forceps' tips in the computational modeling. To justify the data collected from Von Mises' yield condition, the Haigh diagram was developed to analyze fatigue wear. The low cycle loading behavior of the active micro forceps was analyzed in computational engineering tool of ANSYS LS-DYNA under operational load conditions in vitrectomy. The results of the analysis obtained from this research are helpful for micro component manufacturer and clinic surgery operation.
