2D Crack Propagation Based on the Value of Total Energy Release Rate in a Tube | Marc Mentat

The propagation of cracks in a tube subjected to high pressure was analyzed using the direct crack propagation method, which is based on the criteria of the total energy release rate (TERR). The TERR is a measure of the energy required to propagate the crack, and it is related to the stress intensity factor (SIF) at the tip of the crack. The SIF is a measure of the stress concentration at the crack tip, and it is influenced by the material properties, the applied load, and the geometry of the tube.
An analytical method, the Griffith equation was used to predict the SIF and the TERR along the crack path. The Griffith equation is an empirical equation that relates the SIF and the TERR to the crack growth rate, which is the rate at which the crack propagates. This equation is often used to predict the crack growth rate in brittle materials, such as ceramics or metals.

Thank you very much for the tutorial! It was really useful since I couldn’t find any tutorials on crack propagation using Marc.
It would really help and looking forward for another tutorial on 3D crack propagation!

Wow impressive, thank you for the video. As you said at the end it depends on the material properties, so you always welcome to try Total Materia for free to export each individual material properties for your FEA analysis.

By defining the material with the most properties provide quite accuracy in the FEM results.
