A mathematical model has been developed to predict the residual stresses level in pre-stretched aluminum alloy plate. This is based on force balances of the
A mathematical model is developed to calculate the residual stress in stretched aluminum alloy thick plate. It is based on balance of stresses, two-dimensional plasticity and a
One of the most common options for relieving stress comes in the form of heat treatment, and there are a variety of alternatives to choose from. Other possibilities include vibration
Stretching is a typical process performed on solid solution treated aluminum thick plate to release quenching-caused residual stresses through leading uniform
The aim of this study is to investigate the effect of quenching residual stress on the ductile fracture behavior of pre-stretched 7075 aluminum alloy plate. The GTN ductile fracture model is adopted for the failure analysis and implemented in the finite element package ABAQUS. Five cases of plates with different thicknesses are selected
Fig. 2 Pre-stretching simulation model aluminum alloy sheet Fig. 3 Time-varying stress curves in stretching process: (a) σ11-C; (b) σ22-C; (c) σ11-O; (d) σ22-O width direction subtracts just during the stretch process. The reason is that the balanced tensile stress core area decreases with the decrease compressive stress

Release and rebalance of initial residual stress of pre-stretched aluminum alloy plates in processing is the main factor affecting the machining deformation of aeronautic monolithic
A mathematical model has been developed to predict the residual stresses level in pre-stretched aluminum alloy plate. This is based on force balances of the residual stress, theory of plastoelasticity and a new conception of free length. The model is relatively simple because only rolling direction residual stress is taken into account, but provides a clear
The analysis model is established based on the springback analysis of the stretch bending process by considering the coupled effects of bending-induced residual stress and machining-induced stress.

Residual stress distributions in 7075 aluminum alloy thick plates with different thicknesses and different quenching speeds were measured. A shape function of stress distribution was proposed based on the internal stress distribution characteristics of aluminum alloy. Using nonlinear regression technology, the function between stress
A pre-stretching process of 7075 aluminum plates was simulated using FEM method and stress distributions in the pre-stretched plates were obtained. The influence of stretching ratio on residual
Stretch forming equipment produces complex shapes by stretching a metal sheet, plate or extrusion over a form die. Stretch formed parts provide better shape control and surface quality than rolled or drawn parts. Some stretch forming equipment is used to produce aluminum parts for the automobile industry or titanium parts for aerospace
The model is verified against the published experiments performed on 7075 aluminum plate. It is found that the computed residual stress basically express the stress level of the stretched plate
The quenching and pre-stretching process of 7075 aluminum plates were simulated by MSC.Marc FEA program. The quenched residual stress was used as initial condition to apply on the pre-stretch
