1. Die Casting Analysis

• Project Goal
• To analyse the die casting to locate areas with
  maximum stress
• My Approach
• Used Axisymmetric element to minimize
  computations
• The Die was constrained at the top and the loads
  were applied
• The displacement and the stresses in the die cast
  were observed

  deciding the design stress to take into account
  the breaking of glass
• Trials were done with various dimensions to find
  the design which satisfies the design
  requirements
• The displacement and Maximum principal stress
  distribution was observed
