Abstract
EN The use of bonded joints, which is common across many industrial sectors, is closely tied to rapid advances in design and manufacturing technologies. Modern adhesives enable their application under a wide range of operating conditions and allow high precision due to advanced production processes. Different types of bonded joints can exhibit distinct mechanical properties. The behaviour of such joints highlights the critical role of shear stress in fracture. Traditionally, the mechanical performance of bonded joints is analysed through static testing, which provides fundamental mechanical parameters. However, to obtain a more comprehensive understanding, experimental studies should also include other loading conditions, such as dynamic testing. This paper presents the results of both static and dynamic tests on adhesive overlay joints. The original methodology is proposed for testing adhesive joints under impulse tensile force, resulting in an impact shear stress of the joint, which is the dominant regime. The specimens were manufactured from 1 mm galvanised steel strips and bonded with two types of adhesives: DP490 and Hybrid CX80. They were subjected to static tensile tests and dynamic tensile tests using force impulses with varying energies and strain rates. The study provides detailed static and dynamic characteristics of the tested adhesive joints, offering a practical perspective for engineering applications. The proposed testing method can serve as a diagnostic tool for adhesive joints and other types, such as form-fit joints. This can be used as support for the adhesive joint behaviour and data for modelling, manufacturing, and the trade market.
