Week - 4 - 2D meshing for Plastic components

Aim :

For the given Plastic Bottle Cap model, check for the geometrical errors and take the mid surface by suitable mid surfacing techniques. PID and Thickness assignment has to be done for all the mid surfaces. Mesh the same with given element Quality criteria.

Element Quality criteria

S.No	Quality Criteria	Value
1	Target/Average length	1
2	Minimum Length	0.5
3	Maximum Length	3
4	Aspect	3
5	Warpage	15
6	Skewness	45
7	Jacobian	0.7
8	Minimum Quad Angle	45
9	Maximum Quad Angle	135
10	Minimum Tria Angle	30
11	Maximum Tria Angle	120
10	Tria Percentage	15

Steps involved in this challenge:

1. Geometry clean up
2. Mid Surface extraction, Shell property, and Quality assigning
3. Meshing and assigning thickness to it

Before processing

Property and thickness assigning

Property and thickness of the parts are assigned using set PID option.

After Processing

Learning Outcome

• Bottle cap model has been Checked for geomentry and errors.
• Property and thickness assignment to the parts of the bottle cap.
• Meshing the model with the required quality criteria.
• Failure of elements [Off 41] 41 elements failure has helped to learn the type of failure, reason for failure and improvements required for the failure elements.

Conclusion

The Plastic Bottle Cap model has been checked for geometrical errors, extracted themid surface. PID and Thickness assignment has to be done for all the mid surfaces. Meshed the with given element Quality criteria.
