iPhone 5s BENDING USING ANSYS WORK BENCH
TITLE: IPHONE 5S BENDING USING ANSYS WORKBENCH
OBJECTIVE: To perform an bending analysis of iphone 5s.
CASE 1
1.GEOMETRY SETTING
- At first materials are imported from the library.
Aluminium alloy for the frame
Glass for the Display
polyethylene for the interior body of the phone.
- Now I look at the model in Design modular for any error.
- Then I open the model in mechanical modular and assign the materails to the parts.
- Then rename the parts and assign all the fingers on the display as rigid.
- Then I look for pre defined contacts and make some corrections to them.
- Then I define some joints.Fixed to the fingers and translational to pusing fingers.
- Then I look for mesh and use face sizing to fine the mesh.
- Now I define some boundary conditions like fixing the ends of inside parts so during the bending model doesnot translate to any direction.
- Adding 0 mm displacement and fixing towrds x and z direction so it can move only towards z direction.
- Now I difine joint displacemet of the pusing fingers and translate them towards Y direction.
- Now I request for the results.
RESULTS:
DIRCTIONAL DEFORMATION= 8.0048 mm
EQUIVALENT STRESS = 612.16 MPa
EQUIVALENT ELASTIC STRAIM= 0.0090164 mm/mm
CASE 2
In this case I displace the finger to x=22.5mm and z=10mm and define S-N curve for Alluminium Alloy non linear material.
S-N curve for Alluninium Alloy
Now we can look over the new geometry.
- Then all the kind of meshing,analysis as well as boundary condition settings are used same as above simulation.
- Then I request for the results.
NOW WE CAN LOOK OVER THE ANIMATION FILE
RESULTS:
EQUIVALENT STRESS = 1710.6 MPa
DIRECTIONAL DEFORMATION = 8 mm
LIFE= 127.64
FOS= 0.001927
CONCLUSION: Both the models justify their results.No abnormalities can be seen.
