1.4.4.5 Example: Finite-element calculations for a square plate subjected to uniaxial uniform tension

Procedures 5–7 described in Section 1.4.1 will be explained by taking an example of the finite element calculations for a square plate subjected to uniaxial uniform tension, as illustrated in Fig. 1.9. The square plate model has a side of unit length 1 and a thickness of unit length 1, and consists of two constant-strain triangular elements, i.e., the model has four nodes and thus eight degrees of freedom.
