Effects of a strain rate sensitive material on the optimization of an hydroforming process

, 2008
International audienceThe hydroforming process of a T-tube is simulated with the finite element code ABAQUS. The influence of the internal pressure and the axial displacement levels on the final tube quality is evaluated through a "process diagram".

Evaluation of formability and fracture of pure titanium in incremental sheet forming [PDF]

, 2017
A forming limit diagram (FLD) is commonly used as a useful means for characterizing the formability of sheet metal forming processes. In this study, the Nakajima test was used to construct the forming limit curve at necking (FLCN) and fracture (FLCF ...

No wide spread of stellar ages in the Orion Nebula Cluster [PDF]

, 2011
The wide luminosity dispersion seen for stars at a given effective temperature in the H-R diagrams of young clusters and star forming regions is often interpreted as due to significant (~10 Myr) spreads in stellar contraction age.
