Calculates the determinant of jacobian and deformation matrix (B) of quadrilateral element in finite element analysis
This function finds the determinant of the jacobian and deformation matrix (B) of four nodes quadrilateral element in finite element analysis:
function [J_det, B]=Q4(V,r,s)
Input:
V: (4*2) Vertices coordinate matrix. The rows represent each node and columns x-coordinate ,and y-coordinate.
r and s: Values of natural coordinates at the location of integration point.
Output:
J_det: Determinant of the jacobian
B: Deformation Matrix
