OPTIMIZATION OF PROCESS PARAMETERS OF ROTARY FRICTION WELDING OF LOW ALLOY STEEL TUBES USING RESPONSE SURFACE METHODOLOGY

Optimization of process parameters of rotary friction welding of low alloy steel tubes using response surface methodology

Rotary Friction Welding (RFW) is a solid-state welding process that is becoming increasingly popular due to advantages such as low weld heat input, high production efficiency, ease of manufacture, and environmental friendliness.Rotary friction welding can weld materials that are difficult to fuse using fusion welding techniques.The main objective o

No drama in two-dimensional black hole evaporation

We numerically calculate the spacetime describing the formation and evaporation of a regular black hole in 2D dilaton gravity.The apparent horizons evaporate smoothly in finite time to form a compact trapped region.We nevertheless see rich dynamics: berkley power worm 100 pack an antitrapped region forms alongside the black hole and additional comp
