Tension of modified Arcan specimens with different angles of load application with respect to the plane of adhesion was chosen as the experimental method. Experiments are performed at +23 °C. The analysis of the results has enabled us to formulate a linear failure criterion. The data are presented in the form of diagrams applicable to the determination of a safe stress state, not leading to adhesive joint failure. © 2021 The Authors. Published by ELSEVIER B.V.

Introduction Polymeric materials find an ever increasing application in various industries, this being favored by the improvement of production methods and the use of various modifiers. The development of methods and procedures for evaluating various performance characteristics of these materials is becoming important since it would enable us, as early as at the production stage, to predict their ability to resist loads without failure. Using these materials as coatings is a wide area of their application. It was reported in our studies Smirnov et al. (2019) and in elsewhere Barroso et al. (2019), Sharma et al. (2002), Licari (2003) and other that the properties of a polymeric material used as a coating may differ IGF26 - 26th International Conference on Fracture and Structural Integrity Adhesive Strength of an Epoxy-Based Adhesive Joint Under a Complex Stress State Sergey Smirnov a *, Dmitry Konovalov a , Irina Veretennikova a , Aleksander Pestov b a Institute of Engineering Science UB RAS, 34 Komsomolskaya St., Ekaterinburg, 620049, Russia b I.
