How to obtain the stress or strain of a deformable object during deformation

Isaac Sim Version

[!] 4.2.0

Hi, I’ve created some deformable objects in Isaac Sim, and I’m currently looking to measure the stress or strain experienced by these objects during deformation. However, I’ve had difficulty finding any APIs that directly provide access to stress or strain data for deformable objects. I would like to know if it is possible to retrieve such data in Isaac Sim. If this functionality is not available, what would be the recommended approach to evaluate the deformation of a deformable object?
