3 days ago @Yull-1 PyBaMM does have some cracking and degradation models.
You can see if these offer what you need for your work:
I imagine you are looking for features beyond what is offered in those examples, but it could be a start
Description
Hi, I am currently working on battery simulations using PyBaMM and would like to know if there are any existing models that couple electrochemical behavior with mechanical stress, such as models that consider the effects of stress on lithium-ion diffusion or particle cracking due to expansion and contraction during cycling.
Specifically, I am interested in models that can simulate the interaction between mechanical stress and electrochemical processes within the electrode, including aspects like stress-induced changes in ion transport or capacity fade mechanisms due to particle deformation.
If such models are available, could you please provide guidance on how to implement or access them in PyBaMM? Additionally, if there are ongoing developments or planned updates related to this feature, I would appreciate any information on that as well.
Thank you for your assistance.
