linear extrapolation

linear extrapolation

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?

RE: linear extrapolation

use the shape functions associated with the wedge element

RE: linear extrapolation

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
