In the present investigation, commercially pure titanium is welded to AISI 316L stainless steel by intermixing niobium as filler material in a lap joint configuration. For this purpose, pulsed Nd:YAG laser with various pulse durations and peak powers employed obtain different mixing conditions for materials. It will be demonstrated that, despite implementation of material, weld seams are charac...

A literature review has been carried out relating to the damage and fracture behaviour of composite laminates based on woven fabric reinforcement containing a stress raiser in the form of either a circular hole or of a mechanically fastened joint – the tensile failure modes in these two types of problem are very similar. Closed form and finite element based approaches that enable the stress dis...

Lap joints of commercially pure magnesium plates to aluminium plates (Magnesium plate on the top, and Aluminium plate, grade 1100, on the bottom side) were conducted by friction stir welding using various traveling and rotation speeds of the tool to investigate the effects of the welding parameters on the joint characteristics and strength. Defect-free lap joints were obtained in the welding tr...

Corrosion is a significant maintenance problem, especially for aging aircrafts, with the Air Force recently estimating corrosion maintenance costs exceeding $800M per year. Nondestructive evaluation (NDE) techniques can be used to detect corrosion under paint and hidden within layered structures. However, it is difficult to capture a comprehensive picture of the corrosion environment using any ...

Abstract Weight reduction and improved strength are two common engineering goals in the joining sector to benefit transport, aerospace, nuclear industries amongst others. Here, this paper, we show that suitable addition of carbon nanomaterials a tin-based solder material matrix (C-Solder® supplied by Cametics Ltd.) results two-fold soldered composite joints. Single-lap shear joint experiments w...

In this study; experimental failure analysis was investigated on adhesively single-lap joints produced using adhesives reinforced with uni-directional glass fibers. Epoxy adhesive impregnated fiber were used to join composite plates joints. It is aimed strengthen the joint by layers between two plates. The loads of obtained compared attached non-reinforced adhesive. Also, 0o, 15o 30o and 45o re...

Purpose The purpose of this paper is to evaluate and exploit the combination additive manufacturing polymeric technology structural adhesives. main advantage expand maximum dimension 3D printed parts, which typically limited, by joining parts with adhesive, without losing strength stiffness keeping major asset 3 D printing: freedom shape system low cost parts. Design/methodology/approach materi...

This paper is concerned with a fatigue study of composite adhesive lap joints produced from a bi-directional woven E-glass fibres and polypropylene. The adhesive used was a Bostik 7452 (Rubber & Plastics Grade) ethyl cyanoacrylate type. The effects of layer orientation, lap joint length and water immersion on the fatigue behaviour were studied. The specimens were immersed in water during period...
