In this study, a Surface Mechanical Attrition Treatment (SMAT) is applied to 17-4PH single edge notched tension (SENT) sample made by Atomic Diffusion Additive Manufacturing (ADAM). Grating of gold nanoparticles allowing multiscale characterizations deposited on the surface specimen electron beam lithography. In-situ tensile test carried out and images are recorded. The crack propagation follow...

A small tapered slot antenna with a notched band for wireless applications is proposed in this paper. A modified transition from microstrip to slotline is used to introduce a notched band from 4.90 to 6.34GHz. Corrugated edges on the ground is also used to improve the radiation patterns at the lower frequency band. Relatively stable radiation patterns and consistent group delay except the notch...

The Mode I and II Interlaminar Fracture Toughness (IFT) of Vectran/Epoxy composite material were investigated using the Double Cantilever Beam (DCB) 4 End Notched Flexure (4ENF) methods, respectively. Due to relatively low compressive strength Vectran (<10% its tensile properties), specimens hybridised by over wrapping with T800s/M21 prevent failure during testing. Experimental results then sim...

Statement of problem Stereolithography (SLA) ceramic crown frameworks are suitable for clinical use, but the impact SLA build orientation has not been identified. Purpose The purpose this in vitro study was to investigate effect 3 orientations on physical and mechanical properties microstructure alumina dental ceramics. Material methods microstructures different oriented ceramics (ZX, ZY, XY) w...

A novel tapered slot antenna (TSA) with 3.5/5.5 GHz dual band-notched characteristics for ultra-wideband (UWB) radios is proposed in this paper. To realize dual band-notched characteristics at the TSA, we employ (a) a pair of nested C-shaped stubs beside the feed line and (b) a broadband microstrip-to-slot-line transition with an Archimedean spiral-shaped slot. The proposed antenna has been suc...

Stein (1990) discovered (n l)! lattice tilings of R” by translates of the notched n-cube which are inequivalent under translation. We show that there are no other inequivalent tilings of IF!” by translates of the notched cube.

The aim of the current project is to carry out FEA framework for predicting flexural strength notched foam concrete tested under three-point bending following conducted experimental set-up. investigated testing series have a variation notch size opening in foamed beam. Traction-separation relationship was used as constitutive model incorporate independent material properties and modelling frame...

PURPOSE To assess the effects of positioning and notching of resurfaced femurs on the mechanical strength of third-generation saw bone (TGSB) femurs using an in vitro analogue bone model. METHODS 30 TGSB femurs were equally divided into 6 resurfaced femur groups (intact, anatomic, varus, valgus, anatomically notched, and valgus notched) for testing the load to failure, stiffness, and total en...

ID No. : FC-168 ABSTRACT Fiber-reinforced self-healing ceramic (shFRC) [1] is considered to be most attractive candidate of next generation structural materials using at high temperature, e.g. turbine blade, exhaust component of car engine etc. The shFRCs consist of three components, which are oxide fiber bundle, oxide matrix and self-healing agent interlayer. As the self-healing is generated a...
