Week 3 Sheet metal Bending challenge

Sheet Metal Bending Challenge:-

Objective:-

To perform sheet metal Bending operation in Ansys Workbench

1.Geometric design:-

The 3D model is shown below, It is having three parts as Punch, Die, and Sheet

                           Fig 1. Geometry

There will be three cases for analysis:-

Case 1:- Aluminium alloy NL, Magnesium alloy N L, Copper alloy N L.

Case 2:- Aluminum alloy with friction coefficient 0.19 ( other case is 0.1 )

Case 3:- Aluminium alloy with Refined mesh.

2.Mesh Criterion:-

Element type: Tet and Hexa mesh

Body sizing 1: 4mm

Body sizing 2: 2mm

Face sizing: 1mm

Method: Patch conforming method ( Sheet)

3. Boundary Condition:-

Punch and Die sheets possess various contacts, Frictional contact between Punch and sheet, another frictional contact between Sheet and Die.

Punch will be given displacement in the Y direction, and two sides of the Plate are kept fixed with 0 mm displacement, die is constrained with all sides.

4.Contacts:-

                                               Fig 2. Contact 1

                                             Fig 3. Contact 2

5.Displacement settings:-
