Week 1 Stress Concentration on a Plate with hole

Aim: - To determine the stress concentration on a plate with holes using static structural analysis.

1. Objective:-
   1. Make a plate with a hole model on it.
   2. Make a plate with three holes of varying sizes.
   3. In both models, determining the maximum deformation and stress.
   4. On the basis of analysis and manufacturing, comparing the results of two cases and determining which cases to choose.
2. Procedure
   1. Designing geometry in spaceclaim.
      1. 
      2. 
   2. Providing material to the body in static structural.
      1. 
      2. 
   3. Meshing the solid body ( Bodies in both cases are meshed at element size of 7 mm ).
      1. 
      2. 
   4. Giving the boundary condition to the solid bodies in both cases.

4. Comparing the results

   1. Sr. No	Solution	Case 1	Case 2
      1.	Equivalent Stress(maximum)	0.60614 MPa	0.57172 MPa
      2.	Equivalent Stress(minimum)	0	0
      3.	Total Deformation ( maximum )	0.00027482	0.00029716 mm
      4.	Total Deformation ( minimum )	0	0

5. Conclusion
   1. From the above results we conclude that Case 1 ( Plate with a hole ) compared to Case 2 ( Plate with 3 holes ).
   2. Stress is more in Case 1 ( Plate with a hole ) compared to Case 2 ( Plate with 3 holes ).
   3. Conclusion from analysis point.
      1. From analysis point of view plates from both cases can be used because both of them has minimal stress developing.
   4. Conclusion from manufacturing point.
      1. If cost factor is considered case 1 is preferred as less work will be required thus costing will be reduced.
      2. If weight factor is needed to be considered as its also an important factor in automobile industry then case 2 can be selected instead of case 1.
