Radial point interpolation functions
is the estimated value of the solution at x
is the radial basis function
is the coordinate of the i-th node
in the support domain
, known constant,
is polynomial basis function
are the parameters to be sought
to calculate n+m unknown coefficients
Shape function
matrix form
then
: shape function
: the displacement at the nods
Extend to the entire solution domain
Example of shape function
Support domain RPIM shape funtion
