Enrichment functions for weak singularities in 2D elastic problems with isotropic and orthotropic materials

作者：

Highlights：

• Numerical reproduction of the displacement function in adjacency of weak singularities in linear elasticity is developed.

• No information about the singularity order is required to create the enriching terms.

• The technique has a similar routine for both isotropic and orthotropic materials.
