Reinforced Fields of Triangular Elements with Linearly Varying Strain; Effect of Initial Strains

This third technical note, on the background of the author's Main Lecture to the Society(1), illustrates the application of the technique given in ref. 2 on a simple example, and develops the basic ideas further, with particular reference to the effect of reinforcing flanges and initial loads, as may arise through differential thermal straining. A more ambitious example demonstrating the improvement achieved by the new triangle appears in ref. 1.
