New design of process for cold forging to improve multi-stage gas fitting
Advances in Mechanical Engineering, 2016 This work develops a process that solves the problem of the formation of cracks inside forged gas fittings in the cold forging process that arises from poor forging process design. DEFORM-3D forming software was utilized, and macroscopic experiments with

A novel methodology for in-process monitoring of flow forming [PDF]
, 2017 Flow forming (FF) is an incremental cold working process with near-net-shape forming capability. Failures by fracture due to high deformation can be unexpected and sometimes catastrophic, causing tool damage. If process failures can be identified in real

Influence of the constitutive flow law in FEM simulation of the Radial forging process [PDF]
, 2013 Radial forging is a widely used forming process for manufacturing hollow products in transport industry. As the deformation of the workpiece, during the process, is a consequence of a large number of high-speed strokes, the Johnson-Cook constitutive law (

On the Origin of Stellar Masses [PDF]
, 2011 It has been a longstanding problem to determine, as far as possible, the characteristic masses of stars in terms of fundamental constants; the almost complete invariance of this mass as a function of the star-forming environment suggests that this should
