Effect of orientation and pre-tension on stresses distribution on V-die bending processes by finite element method

Abstract EN

Simulation of metal forming processes using the Finite Element Method (FEM) is a well-established procedure, being nowadays possible to develop alternative approaches, such as inverse methodologies, in solving complex problems.

This study investigated the effect of orientation and pre-tension on stresses distribution numerically by software ANSYS 19 using the finite element method.

The pre-tension is 55% from total strained in each rolling direction.

The results show that the orientation has a significant effect on stresses distribution and stress value before and after pre-tension 55% .

Although there is a regular distribution of stresses in three direction, but there is significant difference in the values of stresses in each of (0, 45, 90) degrees.

The highest value of trolling direction.

The pre-tension has a greater impact on stresses distribution and stress value.

Although, there is a regular distribution of stresses in blank before and after pre-tension, but there is significant difference in the values.

Where in 0 degree on rolling directionthe stresses increased by 31.7% from their values before pre-tension, while in 45 degreeson rolling direction the stresses increased by 35.6% and in 90 degreeson rolling direction the stresses increased by 23.6% from their values before to develop alternative approaches, such as inverse methodologies, in solving complex problems.
