Through-Thickness Stresses in Automotive Sheet Metal after Plane Strain Channel Draw
نویسندگان
چکیده
Abstract. A series of samples from four automotive materials AKDQ, HSLA50, DP600, and AA6022-T43 were deformed in a channel draw processes with different levels of draw bead penetration. As a result, varying magnitudes of deformations in plane strain mode and residual stresses were obtained. Through-thickness stress profiles were obtained non-destructively using a novel, high resolution X-ray diffraction technique.

Bending-Unbending Analysis of Anisotropic Sheet under Plane Strain Condition
The mechanical behavior of cold rolled sheets is significantly related to residual stresses that arise from bending and unbending processes. Measurement of residual stresses is mostly limited to surface measurement techniques. Experimental determination of stress variation through thickness is difficult and time-consuming. This paper presents a closed form solution for residual stresses, in whi...

Sheet metal forming is simulated by finite element methods using a stress resultant constitutive law in this paper. A Lagrangian description of axisymmetric and plane-strain shell deformation is first reviewed. Then a stress resultant constitutive law in rate form is presented, where the effect of thickness reduction due to large plastic deformation is considered. A finite element formulation i...
متن کاملFINITE ELEMENT PREDICTION OF DUCTILE FRACTURE IN AUTOMOTIVE PANEL FORMING: COMPARISON BETWEEN FLD AND LEMAITRE DAMAGE MODELS
In sheet metal forming processes with complex strain paths, a part is subjected to large plastic deformation. This severe plastic deformation leads to high plastic strain localization zones and subsequent accumulation of those strains. Then internal and superficial micro-defects and in other words ductile damage is created. This damage causes quality problems such as fracture. Therefore, design...
