Abstract This paper presents a simple experimental validation of method for finding optimal application patterns in adhesive bonding, as previously introduced by Flaig et al. (2023). The study uses two examples to demonstrate that the found theory effectively fill target gaps after pressing practice. results confirm identified almost perfectly, ensuring excellent joint integrity process. In par...

This paper presents an extensive experimental and numerical study on the behavior of CFRP/Steel adhesively bonded double strap joints (DSJ). A total 50 DSJ specimens were tested under static tensile loading. The digital image correlation (DIC) was used to measure backface deformation. six adhesives that feature different stiffness, strength, ductility, toughness analyzed. parametric including s...

Enhanced finite elements are elements with an embedded analytical solution that can capture detailed local fields, enabling more efficient mesh independent finite element analysis. In earlier research, this method was applied to adhesively bonded joints. The adherends were modeled as composite Euler-Bernoulli beams, and the adhesive layer was modeled as a bed of linear shear and normal springs....

The mechanical properties of Z-pins reinforced composites adhesively bonded single-lap joints (SLJs) under un-directional tension loading are investigated by experimental and numerical methods. Three kinds joint configurations, including SLJs with three/two rows “I” array Z-pins, test. failure modes mechanism different numbers alignment analyzed, the comparison is performed for strengths no joi...
