Abstract EN
As a new type of variable thickness sheet structure, the TRB (tailor rolled blank) has good prospects for the development of lightweight materials in the automotive industry.
However, springback is a key issue in production.
Research on TRB springback characteristics has great significance for further applications due to variations in the sheet thickness and gradient distribution of the material mechanical properties.
In this study, the springback characteristics of TRBs were investigated by means of the finite element code ABAQUS/USDFLD and experiments taking cylindrical bending as an example.
The results showed that the cylindrical bending process of the TRB gradually evolved from three-point bending to four-point bending and, finally, to multipoint bending.
At same time, the gradient of the thickness leads to the nonuniform longitudinal distribution of the von Mises stress.
On the contrary, larger bending angles can be achieved by reducing R and improving Rd, but t/T has little effect on the bending angles.
In terms of the influence of springback, increasing Rd and reducing R and t/T can lead to a smaller springback angle.
This project provided an important opportunity to advance the understanding of TRB springback characteristics.
