Shape function in finite element analysis
http://users.metu.edu.tr/csert/me582/ME582%20Ch%2002.pdf WebbA class of finite element method using kriging shape functions is developed to analyze Reissner-Mindlin plates. The shape functions are constructed using kriging interpolation (KI) over a set of nodes encompassing a number of layers of elements. In addition to the commonly used gaussian correlation function, a quartic spline function is introduced as …
