Abstract: The erosion of perfectly brittle materials under low-speed impacts is studied by the combination of the Hertzian contact theory and the maximum stress criterion. It is found that the fractional erosion per impact is ...

Abstract: Ti-6Al-4V titanium alloy manufactured by selective laser melting (SLM) has a unique structure and properties. They offer a higher yield and ultimate tensile strengths but lower ductility than traditionally processed samples. ...

Abstract: In this study, a fractional-order food chain model with disease and two delays is proposed. The existence conditions for a positive equilibrium point are given, and the stability conditions without the effects of delays ...

Abstract: Heterogeneity of material properties is an important potential contributor to bone fracture resistance because of its putative contribution to toughness, but establishing the contribution of heterogeneity to fracture risk ...

Abstract: The goal of this study was to characterize antibody penetration through cartilage tissue under mechanical loading. Mechanical stimulation aids in the penetration of some proteins, but this effect has not characterized ...

Abstract: The ignition transient phase in a model supersonic combustor with transverse fuel injection upstream of a cavity flame holder was experimentally investigated. Three types of ignition processes for scramjet startup were ...

Abstract: The prelithiation of hard carbon electrode using stable metal lithium powder to compensate the lithium loss during the first lithium insertion is studied in this work. The results show that when the pressure on lithium ...

Abstract: Needle–tissue interactive force is vital for developing a virtual simulation and planning system (SPS) and optimizing needle control strategy, wherein the friction coefficient is an important parameter but difficult to ...

Abstract: Gear manufacturing errors are key parameters in planetary gear trains and have effects on load sharing, tooth stress, and so on. Accurate estimation of manufacturing errors can help monitor the conditions of planetary gear ...

Abstract: In this article, proton exchange membranes (PEMs) are used as separators for lead-acid batteries. Ion migration experiments are conducted to prove the efficacy of PEMs in blocking the passage of antimony ions. The cells ...
