) [20,21] of the brazed joints in the plate-fin structure. When performing tensile tests of plate-fin structures, one should take into account that there are two contributions to the strength: one from... involves calculating the following parameters: the sum of squares (SS), degrees of freedom (DOF), variance (V), variance ratio (F), the pure sum of squares (S′) and percent of contributions (P). Further......
