I'm trying to enter a constitutive law for masonry. I have seen that there is the tb command, which allows you to enter an anisotropic constitutional law, which allows you to have different tensions of yield and compression.
However, it gives me an error on the compatibility equation of the deformative field, because, I would like a material with different strain of yield to compr and tens but isotropic, or at least orthotropic. but this leads me to an incompatible deformed configuration.
is it not possible to use the elastic multilinear command to insert a law constituted that goes from a negative value of tension to a positive? because it tells me that the law can only be defined by positive values... does not exist a less "reflected" command of aniso?
