Week 5 Bending of iPhone

Aim- To Perfrom bending of the iphone and obtaining the fatigue life of the material.

Objectives-

1.simulate the model as its given in the video,

2.move the bottom fingers from their definerd position to the given position x=22.5 mm and z=10mm

pre-processing

Geometry

Materials =

Allumnium Alloy

Glass

Polyehthene

connection-

Bounded display to Frame

Frictonless -Rest of all contacts

Joints -

Fixed

Translation -This joint given to below fingers.

Meshing

Face sizing

Analysis settings

Fixed support

Displacement -Displacement along x and Z is restricted so to alloe the motion in the y direction.

Joint Displacemet - Dispalcement of 8mm is given to the bottom fingers

Solver output

Directional Deformation

Equivalent stress Life

Similarly for second case

we have transformed x by 10mm and z by 22mm

rest is same as the previous case

Directional Deformation

Eqivalent stress-

Fatigue Life

Conclusion-

By comparing both caseswe can say that case 2 shows less stress cycle due to loading from the center region .Therefore we can say that case 2 shows better result than the case1 becuse of unifrom loading through the phone.
