TL;DR: In this article, a sequence of fabricating the built-in TFTs and experimental setups are proposed and demonstrated, and cutting experiments are carried out under different cutting conditions for A6061-T6 aluminum alloy and finally cutting temperature is measured at very high cutting speeds up to 16 m/s.

TL;DR: In this paper, a reliable coupled thermo-mechanical and 3D rigid-plastic finite-element (FE) model for hot rolling of large rings is established based on the stable forming condition of the ring rolling process and comprehensive numerical simulations.

TL;DR: In this paper, a meshless local Petrov-Galerkin (MLPG) based analysis of the stiffness matrix of a plate is presented, where each node is surrounded by a cubic sub-domain to which a local integral equation is applied and a weak formulation for the set of governing equations is transformed into local integral equations on local subdomains using a Heaviside step function as test function.

TL;DR: In this paper, the effects of strain rate at quasi-static condition and temperature are theoretically investigated on the FLD of AA3104-H19 aluminum alloy under plane stress condition and considering the through-thickness normal stress effect the forming limit diagram (FLD), stress-based forming limit diagrams (FLSD), and extended forming limit stress diagram (XFLSD) is also studied theoretically based on Yld2011 yield criterion and modified M-K model.

TL;DR: The present study is aimed at selecting proper forming parameters to produce sheet metal parts which possess dimensional accuracy and good surface quality at the shortest time.
