Finite element simulation and experiment in tube hydroforming of unequal T shapes

Internal state variable plasticity-damage modeling of the copper tee-shaped tube hydroforming process

“…Abrantes et al (2005) used FEA to establish a basic understanding of the tube hydroforming process for aluminum and copper tubes. Kashani Zadeh and Mashhadi (2006) used finite element simulations to quantify the effects of coefficient of friction, strain hardening exponent, and fillet radius on the parameters, protrusion height, thickness distribution, and clamping an axial forces. Guan et al (2006) developed and implemented a polycrystalline model into a finite element program and calculated texture evolution on several aluminum hydroformed components.…”

Finite Element Analysis and Experimental Study of Manufacturing Thin-Walled Five-Branched AISI 304 Stainless Steel Tubes with Different Diameters Using a Hydroforming Process

“…For instance, Chunmei et al [ 38 ] coupled three damage models (Lemaitre model, B&W model, and R&T model) with their developed one-surface cyclic plasticity constitutive model for predicting the forming limits in the THF process. Other investigations were performed to examine how the loading path affects failures and explored the influence of the frictional coefficient on protrusion height and thickness distribution [ 39 , 40 ]. Other studies conducted FE simulations to assess the effects of weld geometry, mechanical properties, and tube end conditions on failure location.…”

“…These instability modes, which define the boundaries of formability in the THF process, arise when the stress and strain state in part reaches a critical level. At this point, equilibrium can no longer be maintained between the external forces applied and the internal resistance of the material (i.e., its strength) [38][39][40][41]. There has been considerable analysis in the literature regarding the theoretical modeling of failure types or instability modes.…”

A fast algorithm for strain prediction in tube hydroforming based on one-step inverse approach

“…Kashani Zadeh and Mashhadi (2006) used ABAQUS FE code to quantify the effects of coefficient of friction, strain hardening exponent, and fillet radius on the parameters, protrusion height, thickness distribution, and clamping an axial forces. Yuan et al (2006) investigated via FEM and experiments the hydroforming of automotive rectangular section structural components.…”
