13. An experimental investigation of static load capacity of AL-GFRP adhesively bonded single lap and double butt lap joints
AbstractThis paper is focused on experimental evaluation and comparison of progressive damage behaviors in adhesively bonded single lap and double butt lap joints between aluminum and glass fiber reinforced plastic (GFRP). The effect of joint design and dissimilarity of adherents on damage evolution of adhesive bonding under tensile quasi static loading is a

14. Theoretical modeling of low-attenuation lamb wave modes generation in three-layer adhesive joints using angle beam transducer
AbstractIn this paper, at first the attenuation of Lamb waves in three-layer adhesive joints, including two elastic plates bonded together by a viscoelastic adhesive layer, is investigated using Global matrix method and then suitable incidence angle is theoretically calculated to generate low-attenuation Lamb waves using angle beam transducer. Theoretical bo

15. Failure criterion for adhesively bonded joints using Arcan´s experimental method
Characterization of polymeric materials mechanical behavior requires some previous knowledge about their structure, which allows the choice of more appropriated models and methods. Polymeric materials, below their glass transition temperature (Tg), may be handled as perfect elastic solids, allowing the use of classic mechanics to characterize their behavior.

16. The effect of viscoelasticity on creep behavior of double-lap adhesively bonded joints
The effect of viscoelasticity of epoxy adhesive on creep behavior in the adhesive layer of a double-lap joint is studied in this paper. The joint is comprised of three elastic single isotropic adherend layers joined by an epoxy adhesive that is under shear loading. Prony series is used to modeling the relaxation modulus of epoxy adhesive. The differential eq

17. Bonded Joints Design Aided by Computational Tool
Abstract: In order to aid the design of bonded joints, a computational tool named System of Analysis for Joints (SAJ) was developed. The software can analyze single and double lap bonded joint with composite-composite or metal-composite materials as adherent parts. Thus, SAJ can calculate the stress distribution, loads and displacements. Their results were c

18. Numerical simulations of crack propagation tests in adhesive bonded joints
Mainly due to their low weight, low cost and ease of assembly, the adhesive bonds have emerged as a promising technology. However, the lack of adequate tools of design and control remain an obstacle to the use of the adhesives. In this work a cohesive interface model formulated within the framework of damage mechanics is applied for the simulation of decohes

19. Polyurethane structural adhesives applied in automotive composite joints
In recent years structural adhesives technology has demonstrated great potential for application due to its capacity to transform complex structures into solid unitary and monolithic assemblies using different materials. Thus, seams or joints integrate these structures providing, besides a reduction in weight, a considerable increase in the mechanical resist

20. Análise de tensões e critérios de falha para juntas de estruturas aeronáuticas metálicas coladas / Stress analysis and failure criteria of metallic bonded joints in aeronautical structures
A aplicação de adesivos para união de materiais cresceu consideravelmente no decorrer dos últimos anos, sendo que tal crescimento se deve aos benefícios proporcionados pelos adesivos, quando comparados aos métodos tradicionais de união, como solda ou utilização de parafusos. Na indústria, características como fácil aplicabilidade, melhor distribu

21. Machined and plastic copings in three-element prostheses with different types of implantabutment joints: a strain gauge comparative analysis
OBJECTIVE: Using strain gauge (SG) analysis, the aim of this in vitro study was quantify the strain development during the fixation of three-unit screw implant-supported fixed partial dentures, varying the types of implant-abutment joints and the type of prosthetic coping. The hypotheses were that the type of hexagonal connection would generate different mic

24. Adesivos alcalinamente ativados:ativação com silicato de potássio e silicato de sódio
Known since the 70s, geopolymers are excellent chemical, mechanical and thermal performance materials. Although they have mostly been used as coatings in many of these applications, the number of studies on adhesion mechanisms of geopolymers is considerably less than the use of their properties. The main objective of this work is to evaluate resistance to si
