6.1 Mathematical formulation of engineering
problems
6.1.1 Welded Beam Design Problem Case A
The mathematical formulation of the welded beam design problem is given
in Table 6.1. The schema is shown in Figure 6.1
6.1.2 Welded Beam Design Problem Case B
The welded beam design problem case B is a variation of case A. It is
extended to include two types of welded joint configuration and four possible
beam materials. The changed places with respect to the formulation in Table
6.1 are shown in Equation 6.1.
