how to do a linear extrapolation of stresses from integration points to the nodes in wedge element (6 nodes)?
What is the fuction (linear) to use for this extrapolation?

use the shape functions associated with the wedge element

No matter what types of elements, the extrapolation algorithm is identical. Here are the general steps:
1. get the shape function for your specific element type
2. the value at each node can be calculated by the multiplication of shape function and stress value at integration points
