In Classical Plate Theory, how many triangles assemble to give a conforming triangular element with DOF w, \(\frac{dw}{dy}\) and \(\frac{dw}{dy}\) at each vertex?

(a) 1

(b) 3

(c) 4

(d) 12

This question was addressed to me in an interview for internship.

I need to ask this question from Classical Plate Model in portion Bending of Elastic Plates of Finite Element Method
