DescriptionWood and wood-based components provide excellent mechanical properties (i.e. high stiffness, strength, high resistance against fatigue, low density) paired with low raw material costs. In different applications (e.g. vehicles) it is necessary to join wood-based components and non-wood materials using bolts or screws in order to meet required stiffness and strength. For joining wood-based multi-materials with screws and bolts, however, there are only few studies available which investigated the strength and stiffness of these components. For that reason, in the presented study screwed and bolted double-lap joints pairing plywood and metal sheets were tested in uniaxial tensile experiments. The aim of the study was to investigate the micro- and macro-mechanical behavior of the plywood (beech and birch) with a focus on capturing the stress-strain concentration around the joining area by means of non-contact optical gauging techniques like Electronic Speckle Pattern Interferometry (ESPI). Furthermore, several mechanical properties, such as tensile strength, yield strain, load-carrying capacity, and fracture energy were determined to provide fundamental data for future multi-material components developments and material simulation.
