Within the branch of materials science known as material failure theory, the goodman relation (also called a goodman diagram, a goodman-haigh diagram, a haigh diagram or a haigh-soderberg diagram) is an equation used to quantify the interaction of mean and alternating stresses on the fatigue life of a material.
The design curves for weld details in the bs and cen rules are statistical lower bounds to test data. Therefore, in contrast to the curves for assessing plain materials, they embody known probabilities of survival. This is more in keeping with the design data in most modern fatigue design rules than the use of arbitrary safety factors.
And in a circuit, you can calculate it by multiplying the current by the voltage. We can do exactly the same thing for an ac circuit; we just use the rms current and rms voltages.

Design calculations establish minimum guidelines and requirements for generating electrical calculations on projects. Electrical calculations should be made for all spu projects that include electrical components and should be filed in the project notebook. Design calculations may be made either manually or by spu-approved computer programs.
To apply this method, one only needs to solve a matrix nearness problem that arises naturally from the design specifications. Therefore, it is fast and easy to develop versions of the algorithm that target new design problems. Alternating projection will often succeed even if algebraic con-structions are unavailable.
