Fracture Model
Unstable Fracture - Evaluation of Stress Intensity Factors,
KI
- The Stress Intensity Factors may be calculated using
the J-Integral Method.
- The J-Integral is equal to the Strain Energy release
rate which allows us to employ the Finite Element
Method.
- For the linear elastic case, the J-Integral is the
negative differential of strain energy with respect
to crack surface area.

|
 |
- The finite element method is used to calculate KI
by measuring the strain energy for various crack lengths.
