Week 5 Bending of iPhone

OBJECTIVE:

To simulate the bending of an iphone and find the fatigue life for each case for the applied load.

METHODOLOGY:

• First add the required materials to the engineering data from the material library
• import the geometry to the model and perform the merge operation in the space claim to reduce the no of faces.
• define the frictionless contacts between the contacts and give the bonded contact only between the display and the case.
• 
• give the translational joint to the pushing fingers and ensure that they both translate in the same axis.
• 
• apply the mesh and perform the mesh sizing to the faces of pushing fingers and the back surface of the phone case.
• 
• perform the analysis in 8 steps and give the fixed support to the inside and restrict the motion of case and the inside along the two axes.
• 
• give the joint loads to the pushing fingers.
• 
• run the analysis and check the results and apply the same procedure for the case 2.

CASE 2:

CONCLUSION:

It is seen that the directional deformation is less in case of aluminium alloy non linear with S-N Curve data . So it is better to use this material for frame of a iphone.
