While deposited thin film coatings can help enhance surface characteristics such as hardness and friction, their effective incorporation in product design is restricted by the limited understanding of mechanical behavior. To address this, an approach combining micro-indentation meso/micro-scale simulations was proposed. In this approach, testing conducted on both coating substrate. A meso-scale uniaxial compression finite element model developed to obtain a material coating. This...
Abstract A bolted joint is one of the most common fastening techniques. While behavior joints under static or quasi-static conditions well documented, their shock/impact loading not well-understood. In many applications, where a connects sensitive component to rest structure, it important interpret shock propagation through joints. This problem further complicated owing fact that exhibits multiple types nonlinearities, due interaction between bolts and clamped parts, thread friction shank...
Titanium alloys have been extensively used in the aerospace industry because of their outstanding properties, such as high strength-to-weight ratios, corrosion resistances, and melting points. However, it is hypothesized that performance titanium can be further enhanced to more resistant hypervelocity impact by coating them. Earlier experimental investigations showed a Ti-6Al-4V substrate Ti/SiC Metal Matrix Nanocomposite (MMNC) improved resistance composite. The had 7% SiC volume. These...
Abstract Two-stage light gas guns are used to accelerate projectiles velocities of multiple kilometers per second. These in many applications including experiments understand the response structural components within spacecraft and satellites impacts orbital debris. Obtaining a precise projectile velocity can be challenging due uncertainties associated with these guns. Therefore, most depend on expertise operators estimate mass projectile, main charge, propellent type, piston mass, pump tube...
