Bending of iPhone

Aim:

To simulate the bending of iPhone as per the given cases below

Case 1: Simulate the model as it is given in the video

Case 2: Move the bottom fingers from their defined position to the given position X= 22.5mm & Z= 10mm and obtain the results for the simulation. Also define the S-N curve for the Aluminium Alloy material as per values given below and determine the fatigue life results for the same.

Geometry:

Case 1:

Case 2:

Material:

S.N curve of aluminium was defined in material list .

Connections & joints:

Auto contacts were assigned

Fixed joints for fingers and translation for thumb was defined :

Mesh:

Program controlled mesh face mesh sizing of 4mm was used

Analysis settings :

Total displacement of 8 mm was given

Results:

Total deformation of frame .

Stress:
