The Eberhard Effect

The Eberhard effect, sometimes called the edge effect, occurs during the developing process when a dense image is being produced. During developing a concentration of reaction products and an exhaustion of developer can

More recent studies by Dupont and co-workers, using the palladacycle D, and Eberhard," using several monomeric chelates, such as E and F, indicate that these systems decompose to Pd(0) species under normal reaction conditions. In both cases, Hg(0) stops the reaction, and Eberhard showed that CSj, thiophene and PPhj are effective poisons, even at 180°C. 

Yield drift obtained through Eq. 3 is generally evaluated as the comer for an ideal envelope approximating a bilinear force deformation response of the element and not as the drift corresponding to the first yielding in the reinforcement steel (or equivalently in the concrete) at the first section of the element. Figure 3 shows the procedure by Elwood and Eberhard (2009) for the definition of yielding displacement on the envelope of measured lateral load-displacement relationship corrected for P-delta. Elwood and Eberhard s procedure covers both the cases in which yield force is attained in the envelope (Fig. 3a) and cases in which the calculated yield force is not attained (Fig. 3b) in fact, it provides an estimate of effective stiffness also in the case of columns that do not yield (see Fig. 3b).
