This paper presents a finite element numerical method to assess the stress state and gradients induced by thermo-oxidative ageing in Ti/epoxy/Ti adhesively bonded joints for aircraft engine applications. The is dealing with couplings between thermal, chemistry mechanics occurring during high-temperature of joint, taking into account post-curing stresses, under mechanical loading. Calculations a...

In this study, shear and peel stress distributions in the viscoelastic adhesive layer of a single-lap joint (SLJ) with functionally graded (FG) adherends are investigated. The study focuses on the effect of different adherend profiles and material composition on the time-dependent stress concentration/distribution in balanced and unbalanced SLJs. For this purpose, the Reddy model is applied to ...

For adhesively bonded joint security and long-term use of the joint, a precise stress analysis must be performed on single-lap joints. A formed by joining two layers at given lap length, is most widely used adhesive type in practice. Nowadays, it stated that mechanical properties strength can increased adding clay graphite to polymeric material joints, trying estimate for various loading condit...

The failure in structural adhesively bonded lap joints can be analyzed following different approaches: using a nominal stress state typically given by Strength of Material models, a local singular stress state induced at the mutimaterial corners of the joint, or using cohesive constitutive laws for the adhesive layer or other damage progression models. The aim of this paper is to analyze the su...

An experimental investigation of the load-bearing behavior and ductility FRP hybrid double-lap joints composed both adhesively-bonded bolted connection parts was conducted. Amongst other things, effects adherends’ fiber architecture (uni- or multidirectional), adhesive type (stiff flexible), displacement rate were examined. The resistances with flexible corresponded to full summation bonded par...

Synopsis Composite materials are increasingly used in structural applications within the marine industry. Due to the geometric complexity of marine structures, there is a practical requirement that they are assembled by joining smaller component pieces using either mechanical fasteners or adhesive bonding. In this paper Digital Image Correlation (DIC) is used to provide full-field analysis of t...
