Influences of residual stresses and initial distortion on

In addition to the alloy s deformation and hardening responses during creep-ageing, springback of sheet metals under the warm forming condition is also sensitive to various process parameters (Kim and Koç,. 2008). More relevant of these to CAF are friction

The temperature influence on the mechanical behaviour of this aluminium alloy is described by the thermo-elasto-plastic constitutive model presented in Section 3.

Jun 03, 2019 Warm forming is one of the most promising technologies and it has been studied for many years, with increasing attention of the scienti c community over recent years. This is a consequence of its advantages, namely the increase of the ductility and decrease of the springback e ect in the sheet metal forming of aluminium alloys [1].

Springback analysis of AA5754 after hot stamping: experiments

et al. [12] studied the mechanical behaviour and springback of AA5754-O under warm forming conditions using cup drawing tests. They reported that the tangential stress in the cup wall was the main factor affecting springback. All these previous studies have revealed that springback decreased for warm forming conditions compared with that at room

alloy series, are increasingly implemented in vehicles. These alloys, however, exhibit low formabil-ity and experience considerable springback when formed at low temperatures, and thus have to be formed at elevated temperatures. Severe adhesion and galling are known to be critical tribological challenges in hot forming of aluminium.

brief, warm forming conditions may reduce the flow stress and rate of work hardening, improving the material ductility and toughness. The Aluminium Alloy EN AW 6016-T4 is used in this study. This alloy is commonly used in the automotive industry. It is known as a Si excess alloy since Mg/Si ratio in mass fraction percentage [wt.%] is less than one.

Apr 29, 2020 Such outer panels are usually produced with press forming so that large springback due to the small Young s modulus and stretcher strain mark often become problems at cold forming. Warm temperature press forming, therefore, is known as an efficient technique to overcome such drawbacks of aluminum alloy sheet.

The mechanical behaviour of the metallic sheets at warm temperatures needs to be studied to develop adequate constitutive models.

STATISTICAL EVALUATION OF THE INFLUENCE OF TEMPERATURE AND

Warm temperatures in the forming process ensure better formability of aluminium alloy sheets. After evaluation of the studies found in the literature, it can be concluded that temperature is an important parameter in the forming of aluminium alloys and that influences of surface roughness have not been adequately analysed.
