Electromagnetic forming (EMF) is a kind of high-speed technology that can be useful for materials like aluminum. EMF helps to overcome the limitations traditional forming. Due this ability, use in automotive applications has risen recent years. The application finite element software packages such as ANSYS 22 gives numerical modelling capabilities simulate process and design process. Hence, aim...

Hole is the most common symmetrical geometric structure of mechanical parts, and aperture hole center distance are important measured dimensions in machining. However, existing visual measurement methods often require high equipment installation accuracy low accuracy. To solve problem projection deformation hole: Firstly, a local coordinate system created, plane parallel to end face hole. Secon...

this study is focused on investigating the parameters of laser percussion drilling process of nickel-base super alloy inconel 718 with thickness of 1 mm. fiber laser with the power of 500 watts was used as the laser source. laser pulse frequency, duty cycle, laser power, focal point position, were assumed as the laser drilling process variables. the hole geometry features, i.e. entrance hole di...

Abstract We investigate the weak and strong deflection gravitational lensing by a quantum deformed Schwarzschild black hole find their observables. These observables are evaluated detectability of deformation is assessed, after assuming supermassive holes Sgr A* M87* respectively in Galactic Center at center M87 as lenses. also intensively compare these findings with those renormalization group...

The high energy thermodynamics of Little String Theory (LST) is known to be unstable. An unresolved question is whether the corresponding instability in LST holographic dual is of stringy or supergravity origin. We study UV thermodynamics of a large metric deformation of the LST dual realized (in the extremal case) by type IIB fivebranes wrapping a two-sphere of a resolved conifold, and demonst...

In this manuscript, we consider a deformation on the Heisenberg algebra and investigate effects thermodynamics of Schwarzschild black hole that is surrounded by quintessence matter. To end, obtain temperature, entropy heat capacity functions using standard laws thermodynamic according to considered deformation. We show upper lower bound values appear these based deformed algebra. Then, derive c...

In the present research, the mixed-mode fracture mechanics analysis in a plate with central hole under tensile loading is considered. It is assumed that a plate containing two symmetrical hole-edge cracks is bonded with two dissimilar planes. The stress intensity factors at the crack tips are calculated. The problem is modeled in Casca software and this model is analyzed with Franc software. Th...

We discuss the stability of (charged) static black holes in higherdimensional spacetimes with and without cosmological constant by using gauge-invariant master equations of the Schrödinger equation type for black hole perturbations derived by the authors recently. In particular, we show that the stability of higher-dimensional Schwarzschild black holes can be proved with the help of a technique...

We present calculations of the g factors for the lower conductance steps of three-dimensional hole quantum wires. Our results prove that the anisotropy with magnetic field orientation, relative to the wire, originates in the Rashba spin-orbit coupling. We also analyze the relevance of the deformation, as the wire evolves from three-dimensional toward a flat two-dimensional geometry. For high en...

A non-contact measurement method, namely electronic speckle pattern interferometer (ESPI), was used to investigate the tensile strain field of a composites plate in the presence of stress concentrations caused by a geometrical defect consisting of circular hole. ESPI uses the principle of 3D speckle interferometry to measure the deformation and contour of the measuring field with submicrometer ...
