This study focused on the optimization of Al—Mg to CuZn34 friction stir lap welding (FSLW) process for optimal combination of rotational and traverse speeds in order to yield favorable fracture load using Grey relational analysis (GRA). First, the degree of freedom was calculated for the system. Then, the experiments based on the target values and number of considered levels, corresponding orth...

This research aimed to determine riveted carbon/epoxy composites’ mechanical performance when fabricated by resin transfer molding (RTM). As this manufacturing process is gaining importance in the aeronautics and automotive industries, assembly methods their reliability must be studied terms of airworthiness transportation implementation. The study case resumes determination bearing strength RT...

The objective of this paper was to investigate the performance of recessed single-lap joints with dissimilar adherends through the finite element method. The influence of material and geometric nonlinearity of the adhesive as well as the impact of the recess length was examined in terms of maximum principal stresses. The strength of the joint was obtained as the load to initiate the crack propa...

The purpose of this paper is to numerically investigate the fatigue life and crack growth path 2024 aluminum plate riveted joints. For purpose, according field observations, parameters affecting are obtained. Relevant geometric such as rivet shank length, hole diameter dimensional tolerances, well location pattern rivets material joints studied. In study, modeling performed calculate equivalent...

Joints and interfaces are one of the key aspects design production composite structures. This paper investigates effect adhesive–adherend interface morphology on mechanical behavior wavy-lap joints with aim to improve performance. Intentional deviation from a flat joint plane was introduced in different bond angles (0°, 60°, 90° 120°) were subjected quasi-static tensile load. Comparisons made r...

This paper considers the bonded joint as a multilayer structure that is analysed using the Transfer Matrix method. In this particular case three layers (two adherents and the adhesive) are considered. The study of this propagation problem may be developed from matrix formulations which describe elastic waves in layered media. This technique combines the theory of the dynamics of the continuum w...
