Fig. 16. Trend of the peel stress σ z [MPa] in simply

adhesive bonded joints and hybrid joints for the three applied

external loads.

In Fig. 17 longitudinal ( σ x ) and transverse (

σ y ) stresses acting in the adhesive volume are shown.

Fig. 17. (a) Longitudinal ( σ x ) and (b) transverse ( σ y ) stresses [MPa] acting on the adhesive volume

(always for an applied external load

of 3000 N).

Also the shear stress τ xz showed peaks at the edges of the

overlap zone and then reducing at the hole (Fig. 18).
