Cracks¶
- Advanced topic: Only covered after Bachelor’s and Master’s level courses
- Rare topic: Most FEA does not focus on cracks, since cracks are due to failure of the initial manufacturing stage and hence crack FEA is an after-thought
Crack Properties¶
| Characteristic length | |
| Fracture energy | Proportional to mesh size How much energy required to break one finite element |
| Displacement |
