Question:
Determine the Jacobian matrix [J] and its determinant for the elements shown in Figure P10-11. Show that the determinant of [J] for rectangular and parallelogram shaped elements is equal to A / 4, where A is the physical area of the element and 4 actually represents the area of the rectangle of sides 2 × 2 when b = 1 and h = 1 in Figure 6-20.
Figure P10-20
