The transient scattering of in-plane elastic waves from a finite-sized periodic structure, comprising regular grid Swiss-cross holes arranged according to square lattice, is considered. theoretical and numerical modelling focuses on the unexplored ultrasonic frequency regime, well beyond first, wide, locally resonant band-gap structure. Dispersive properties array, determined by Bloch–Floquet a...

The development of additive manufacturing (AM) technology is expected to transform product design and manufacturing. It is predicted that the effects of AM on business will be diverse and extensive. It will be critical for business owners to observe how AM impacts on conventional supply chains and business networks, plus the effects on customers’ value propositions and on value creation. Value ...

The components which were assumed to be very difficult to produce or manufacture some years ago can now be made easily using additive manufacturing technology. Additive Manufacturing offers many advantages in the production of parts, presenting freedom for design with the ability to manufacture single or multiple components from a wide range of materials. Different techniques of additive manufa...

Radiology departments are uniquely positioned to perform 3D printing. In this presentation, a practical overview of this emerging technology and its opportunities will be discussed. 3D Printing Technologies Peter Constantine Liacouras PhD (Presenter): Nothing to Disclose LEARNING OBJECTIVES 1) Understand the basic principle of Additive Manufacturing (3D Printing) and how it differs from subtrac...

Abstract Cold spray (CS) can produce thick coatings and free-standing bulk materials is adaptable to additive manufacturing, including on-site repair. However, the structural applications of CS have been limited by inherently incomplete interparticle metallurgical bonding in materials. In this work, an ultrasonic washing test (UWT) was used semi-quantitatively assess extent Al6061 Al2024 relati...

In this work, an innovative manufacturing approach that includes a fully linked and integrated system consisting of laser-based directed energy deposition (DED-LB/M) module forming press is presented. The alternating additive (AM) process based on combination DED-LB/M using laser power 600 W feed rate 400 mm/min subsequent process, in which the structure upset with hydraulic constant force 500 ...

In recent days, additive manufacturing (AM) plays a vital role in component compared to subtractive manufacturing. AM has wide advantage producing complex parts and revolutionizing logistics panorama worldwide. Many researchers this emerging methodology with the conventional found that it helps meeting demand, designing highly components, reducing wastage of materials, there are variety process...
