Question

What is meant by Iso-parametric elements? Explain its types.

Answer 1

The element defined by such a method is known as an isoparametric element. This method can be used to transform the natural coordinates of a point to the Cartesian coordinate system and vice versa.

3 or "8 Node Quadrilateral": 8-node isoparametric rectangular elements (quadratic) 4 or "6 Node Triangle": 6-node isoparametric triangular elements (quadratic) 8 or "9 Node Lagrange": 9-node Langrangian rectangular element (quadratic) (9 point Gaussian quadrature)
