Originally posted by **SebfraOslo** October 19, 2022 Hi, Is it possible to specifiy plane stress or plane strain conditions in the scikit-fem elastic model (linear_elastcicity and linear_stress)? Thank you Sebastien

The first job is to derive the constitutive equation for plane stress. As we are using the Lamé parameters in skfem.models.elasticity, it would make sense to do it here also.

@SebfraOslo actually now I'm wondering if #941 is enough?

SebfraOslo commented 1 year ago

Yes, it is working. It passed my tests.

Thank tou Sebastien
