“…It is coupled with calculation of metallurgical phases distributions followed by the solution of the mechanical problem by the finite element method. The ABAQUS software linked to many subroutines is used to simulate heat treatment phase transformation histories and strain fields as mentioned by Yaakoubi et al (2013b). The thermal cycle recorded by Coret et al (2002) is used as the boundary condition to carry out the simulation (Fig.…”

This study addresses the task of predicting the transformation plasticity induced during phase transformation of the 16MND5 carbon steel from austenite to bainite under low externally applied stress using a semi-theoretical model based on the Greenwood-Johnson mechanism. Both models proposed by Leblond et al. (1989) and Taleb and Sidoroff (2003) sufficiently describe the evolution of the TRansformation Induced Plasticity (TRIP) during continuous cooling of the austenitic phase. Nevertheless, TRIP values predicted by these models underestimate measured data through the first half of the transformation and overestimate them through the second half. So, we propose in this paper a method to improve Taleb's model in order to remove discrepancies between theoretical and experimental results throughout the whole transformation and obtain a better description of experimental data.

“…After completion of the process and during elimination of forming loads, the elastic portion of total imposed strain is recovered and leads to a dimensional deviation in formed part. This phenomenon is known as spring-back that can directly influence the dimensional accuracy and geometry of desired workpiece which leads to major incompatibilities in assembly phase [11]. Therefore, the quantitative make a prediction precisely and compensation of spring-back is a crucial stage in die designing process.…”

Abstract:Flexible roll forming is a high efficiency sheet metal forming process for producing variable cross section profiles.Also spring-back is one of the most important problems in flexible roll forming process. Spring-back is severe during the unloading phase of bending and greatly affects the forming accuracy of the bending parts. In this paper, the spring-back of the flexible roll forming in different temperature have been studied using finite element analysis. The simulation is elaborated by using ABAQUS software linked to elastic-plastic modules which we developed taking into account of interactions between these fields. According to finite element analysis results, the bending after roll forming has been analyzed. Therefore, we can make the comparison of the spring-back and forming force under different temperature from the finite element analysis. A flexible roll forming setup was developed and some parameters in the simulation have been discussed. AZ31 magnesium alloys were used in the simulation and assumed the material is isotropic.
