Surface composite layers were successfully fabricated on an A 1050-H24 aluminum plate by dispersed iron (Fe) and magnetite (Fe₃O₄) particles through friction stir processing (FSP). Fe and Fe₃O₄ powders were packed into a groove of 3 mm in width and 1.5 mm in depth, cut on the aluminum plate, and covered with an aluminum sheet that was 2-mm thick. A friction stir processing (FSP) tool of square ...

In situ fracture study of a Cu/Al composite laminate was discussed via the observation of scanning electron microscope (SEM). The experimental test was carried out by a modified miniature tensile device. With the aid of the SEM’s sample stage and a wedge block, the profile morphology of the specimen was observed. The substrate layer (1060 aluminum) and the plate layer (C11000 copper) of the spe...

Abstract The finite element model is established based on the bench test of landmine blast protection package. effect air gap between package and base plate as well stiffness deformation are investigated. Aluminum sandwich packages designed effects suppression studied using model. results show that not conducive to plate. Increasing benefit plate, however, it necessary consider influence corres...

We report the development of a tactile display made from audio speakers and aluminum plates and having high spatial and temporal resolution. Aluminum plates with thickness of 0.5 mm are attached to audio speakers and aligned at intervals of 1 mm, and skin is deformed perpendicular to the plate direction. The device presents skin deformation with a wide frequency range (10–320 Hz) when a finger ...

We examined a simple screening method for judging the complex formation between a drug and aluminum(III) on a spot plate. As few drug had color reaction by basing on the binary complex formation of drug-aluminum(III), the ternary complex formation of drug-aluminum(III)-dye was studied this time using 50 kinds of drugs. The dyes used were Chromazurol S and Erythrosin. As a result, in the drug th...

A systematic study of acoustic emission detection using fiber Bragg grating sensors is presented. In this, we attempt to use the fiber Bragg grating to sense the dynamic strain created by a passing ultrasonic wave signal. Our goal is to see if such a sensor is possible, and if so, what the detection sensitivity and limitations will be. To answer these questions, we carried out several experimen...

A preliminary study of the feasibility of using piezo-transducer arrays, for detecting flaws in flat aluminum plates and steel tubing, is being performed at The University of Tennessee. The sensor arrays are designed for embedding in aluminum plates and brass tubes. Various forms of defects are placed on the test specimens. Preliminary experiments are carried out using both flat aluminum plate ...

Indonesia is the largest archipelagic maritime country in world, it should strengthen its ability to secure a very wide territorial waters, order ensure security and safety of shipping Indonesian jurisdictional. PC 40 ship reliable TNI-AL patrol with relatively small dimensions will be easy operate areas. In general, structural construction on conventional ships, along times, Sandwich Plate Sys...

The Casimir force between an aluminum-coated plate with small sinusoidal corrugations and a large sphere was measured for surface separations between 0.1 and 0.9 mm using an atomic force microscope. The measured force shows significant deviation from the perturbative theory. The measured Casimir force between the same sphere and flat plate shows good agreement with the same theory in the limit ...
