computeFeatures_numpy(F11, F12, F21, F22):
computeFeatures_torch(I1, I2, I3, Ia, Ib):
Compute the features dependent on the right Cauchy-Green strain invariants. Note that the features only depend on I1 and I3 for plane strain assumption.
Input Arguments
-
I1- 1st invariant -
I2- 2nd invariant -
I3- 3rd invariant -
Ia- Invariant along anisotropy direction. -
Ib- Invariant along second anisotropy direction.
Output Arguments
x- features
get_mass_type():
get_theta_gt(fem_path, feature_filter):
Returns the true feature coefficients corresponding to the benchmark material.
getNumberOfFeatures():
Compute number of features.
Input Arguments
- none
Output Arguments
features.shape[1]- number of features
