Hello!
I am trying to write my own non-linear (geometry and material) FE code to solve large biomechanical problems. I am mostly interested in irreversible effects so I use the multiplicative decomposition of the deformation gradient. I model the elastic bit of my systems with Hencky...
Greetings,
I am a new user and I would firstly like to say hello, and thanks in advance, to everyone here!
I am trying to implement a transverse isotropic hyperelastic material with an UANISOHYPER_INV and I also need to declare initial stresses in my simulation (I do it with a SIGINI...
