The composite T-Joint model is subjected to internal pressure on the inner faces of the hollow cylinders. You perform failure analysis of the T-joint for an initial 8-layered [0/45/90/-45]2 laminate. You increase the model thickness to a 16-layered [0/45/90/-45]2s laminate to improve the factor of safety.

In this lesson, you learn:
- Defining hollow cylinders as composite shells
- Adjusting composite orientation option
- Checking laminate stacking direction
- Viewing stress across different plies along material directions
- Using composite failure criterion to view factor of safety plot
- Altering composite layup to improve factor of safety
