Week 5 Bending of iPhone
Static Analysis on Bending of iPhone using ANSYS Workbench...
Material Used for both the Cases :-
1. AL Alloy NL :- used in Frame.
2. Glass :- used in Glass of the I-phone.
3. Polyethylene :- used in inside of the Mobile.
4. Structural Steel :- used for Fingers.
Meshing for both the Cases :-
Mesh Size :- 4 mm on the back side of the Frame and in pushing finger's.
Analysis Setting For both the Cases :-
Case 1: Simulate the model as it is given in the video.
Fixed & Translational Joints :-
Fixed Support & Displacements :- Fixed support is applied in inside material of the I-phone, So that Frame can't be able to flyoff by applying the displacement.
1. Directional Deformation (on Frame) :- Max. = 5.4227 & Min. = -0.85879
2. Equivalent Stress :- Max. = 795.3 MPa & Min. = 5.7031e-7 MPa
3. Equivalent Stress (on Frame) :- Max. = 600.2 MPa & Min. = 6.941 MPa
.
4. Equivalent Strain (on Frame) :- Max. = 0.0089665 & Min. = 0.00021064
5. Pressure :- Max. = 311.19 MPa & Min. = -221.64 MPa
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.
Contact :- Frictionless & Bonded :- only "Display To Frame" is in "Bonded".
Fixed & Translational Joints :-
Fixed Support & Displacements :- Fixed support is applied in inside material of the I-phone, So that Frame can't be able to flyoff by applying the displacement.
1. Equivalent Stress (on Frame) :- Max. = 345.79 MPa & Min. = 8.3208 MPa
2. Equivalent Stress :- Max. = 660.35 MPa & Min. = 7.166e-7 MPa
3. Equivalent Strain (on Frame) :- Max. = 0.0051015 & Min. = 0.00041507
5. Directional Deformation (on Frame) :- Max. = 4.4939 & Min. = -0.48018
6. Safty Factor :- Max. = 15 & Min. = 0.80974
7. Life :- Max.= 1e8 & Min. = 0
8. Pressure :- Max. = 221.04 MPa & Min. = -345.79 MPa
Result & Conclusion :-
As we see from the above result;
For Stress on Frame :- (Case 2 < Case 1) Stress on the Frame of the I-Phone & in whole body of the I-Phone is less in Case 2, besause in Case 1 the force applied on I-phone through pushing fingers are near to the edge of the phone, which is irregular & In case 2 force applied in the middle of the I-phone, which is Uniform applied. So stress distribution is uniform/ in proper way in Case 2.
For Safty Factor :- For maximum , in both the cases are same, but for minimum (Case 2 > Case 1).
So, from both the condition,we can judge and select the Case 2 is showing better result than the Case 1.
Thus, the Bending of I-phone Simulation is performed for Stress, Strain, Directional Deformation, Safty Factor & for the Life of AL Alloy NL with the help of ANSYS Workbench for the betterment of the research & product development.
