Topology optimization is computationally demanding that requires the assembly and solution to a finite element problem for each material distribution hypothesis. As complementary alternative traditional physics-based topology optimization, we explore data-driven approach can quickly generate accurate solutions. To this end, propose deep learning based on 3D encoder-decoder Convolutional Neural Network architecture accelerating determine optimal computational strategy its deployment. Analysis...
The rotary tool is a recent innovation of PMEDM. Aluminium oxide (Al2O3) powder with particle concentration 0.5–1.5 gm/l was added into the dielectric to study improved machining performance. Inconel 718 machined using copper–tungsten electrode rotation about 300 rpm. Experiments were designed Taguchi's three-level L18 orthogonal array. A mathematical model developed correlate influences these variables such as Peak current (Ip), Sparking gap (V), Pulse on time, (Ton), duty cycle and slurry...
Depending on processing conditions, laser powder bed fusion (LPBF) is known to have two operational regimes - conduction mode and keyhole mode. Heat the dominant heat transfer mechanism for mode, whereas convection In addition, there exists a transition which lies between wherein dominance of or depends upon conditions. this work, normalized diagrams are obtained visualize three melting modes The from work shown be independent material specific classes materials, LPBF system, modulation,...
Abstract Additive manufacturing (AM) enables new possibilities for the design and of complex metal architectures. Incorporating lattice structures into part geometries can enhance strength-to-weight surface area-to-volume ratios valuable components, particularly in industries such as medical devices aerospace. However, their interconnections may result unsupported down-skin surfaces, potentially limiting manufacturability by AM technologies, laser powder bed fusion (LPBF). This study aimed...
Medium/High‑carbon steels are considered susceptible to cracking during rapid cooling in laser powder bed fusion (LPBF) applications. Also, water-atomized (WA) steel powders, containing oxides, have been associated with porosity defects this process. In study, LPBF was employed process WA high‑carbon low-alloy powders under three operational regimes – conduction, transition, and keyhole modes. Analyses based on the scaling law of stability, melt pool dimensions, x-ray computed tomography...
Abstract From the results of mixing trials with a highly instrumented BR Banbury and biconical rotor rheometry mixed batches, detailed analysis flow characteristics in region wing has been undertaken. An ‘angled spreader blade’ analogy is proposed as being viable basis for mathematical modelling. A one-dimensional used, which power-law behavior isothermal conditions are assumed. Dispersive mixing, depends on stress levels generated during shown to occur throughout entire mass material swept...
Abstract An understanding of heat transfer in a bladed mixer is important for drying pharmaceutical drug crystals. This study presents thermal imaging experiments the particle bed surface to investigate how impeller speed influences rate and uniformity transfer.

Laser powder bed fusion (LPBF) of 18Ni-300 maraging steel has attracted abundant popularity in both academia and industry due to its superior mechanical properties printability. Several studies showcased the optimization process parameters based on relative density, but there is little exploration tailoring as-built microstructure. In this study, fully dense samples are fabricated with three different melting modes, they examined for cellular solidification microstructure, retained...
Aluminum 7075 alloy (AA 7075) is one of the prime materials used in aviation and automotive industry because its high strength to weight ratio, good amount fatigue machinability. Friction stir processing (FSP) emerging solid state process that refines microstructure hence improved mechanical properties are obtained. The temperature during FSP affects resulting so attempt for reducing can result into reduction grain size. fine size delivers percentage elongation which reduces number joints...
A major impediment to high-bit-rate wireless transmission is multipath delay spread. Orthogonal frequency division multiplexing (OFDM) addresses this impairment, transmitting several parallel lower bit rate streams. Independent transmit and receive oscillators create offset, generating interchannel interference degrading performance. Several offset estimation techniques have been proposed but varied test conditions make comparison difficult. Here, we compare these schemes under identical...
