The Influence of the Joint Thickness Upon the Impact Strength of Block Adhesive Joints

The research described in this article relates to one of the aspects of methodology of investigating impact loading in block bonded joints. The authors checked experimentally the effect of the thickness of adhesive joints upon impact strength of the connection. The experimental research was completed with preliminary dynamic numerical calculations of the test cases. The experimental testing was conducted with a pendulum hammer designed to examine adhesive joints. The maximum energy of the pendulum used in the investigation equaled 15 J. In order to determine the impact strength of the examined connections, it was used a dependency according to which the energy used to detach the upper element of the sample in such a test, that is the energy lost by the pendulum, is the measure of impact strength of the adhesive joint. The elements of the samples were made of steel S235 or an aluminum alloy 2017A. In order to bond the samples, was used Epidian 57 epoxide resin with Z1 hardener. The models for numerical computations were prepared on the basis of samples used in the experimental research. The prepared models, taking into account the initial and boundary conditions were subjected to dynamic numerical computations by means of the finite element method with the use of the Explicit Dynamics module in the ANSYS programme. The aim of the numerical calculations was to compare the compliance of the results of the experimental and analytical investigations as well as the assessment of the impact of the size of boundary conditions, which were subjected to parametrization, upon the values of occurring stresses during the conducted impact loading simulations. The results of the experimental investigation indicate that along with increasing the thickness of the adhesive joint, impact strength of the connection is reduced, regardless of the bonded material.
