Abstract: Liquid impact forming (LIF) is a rapid tube hydroforming technique. The deformation behaviour of a metal tube may be different in LIF from that in tube hydroforming. A constitutive equation or equivalently an equivalent stress-strain… read more here.

Abstract: Abstract Thickness deviation in hoop direction is often observed in thin-walled extruded tubes, which is mainly due to the eccentric position of extrusion mandrel. This imperfection in thickness may result in different deformation pattern and… read more here.
