Deformation behavior of anisotropic TA18 titanium alloy tube in hydroforming process at room temperature

open access: yesAdvances in Industrial and Manufacturing Engineering
While hydroforming of titanium alloy at room temperature is difficult due to its high strength, low hardening capacity, and significant springback, it is typically deformed into desired shape under high-temperature conditions exceeding 500°C, which ...

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

open access: yes, 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".

Material selection for a new type of fire extinguisher [PDF]

open access: yes, 2011
Nowadays safety is a hot topic, damage inflicted to human beings is intolerable. Fire safety is a big concern in industrial areas, but in residential areas a lot less precautions are in place. Therefore a new type of fire extinguisher should be developed
