Shape Functions of a Constant Strain Tetrahedron

mohamedlamine's picture

Hello,

I have developped a New Method to Compute Numerically the Shape Functions of a Constant Strain Tetrahedron from the Geometrical Information of its Vertices using the Planes' Equations Defining the Barycentric Coordinates versus the Cartesian Coordinates. The Algorithm for Solving the Linear Systems of Equations has been Implemented Efficiently with the Partial Pivoting Gauss LU Method for any arbitrary Shaped and Non-Degenerated Element.

References: FEOFS2013, CanCNSM2013 and FDM2013.

 

Best Regards.
