Hybrid sheets of 1-mm-thick EN AW-6016-T4 aluminum alloy and 4-mm-thick birch wood were produced by adhesive bonding. Wood fibre orientations parallel as well as perpendicular to the rolling direction of the aluminum sheet were considered. After curing the adhesive, the hybrid aluminum-wood sheets with overall dimensions of 250 mm × 60 mm × 5 mm were subjected to three-point bending. Hybrid sheets (i) as fabricated at room temperature, (ii) moistened at room temperature, and (iii) moistened at approx. 100 °C were tested. Two bending modes were investigated, since either the aluminum sheet or the wood sheet was placed at the punch side. Moreover, a finite element model of the testing setup was built using the LS-Dyna software. Experiments were performed for determining individual properties of aluminum and wood which were used as input for the model. Punch force-displacement curves and deformation behavior observed in experiments and simulations showed good agreement.
