Maternal-Infant Bonding: A Joint Rebuttal

Pediatrics, 1983
Inaccuracies in Lamb's recent review1 of studies of maternal-infant bonding have resulted in considerable confusion and misunderstanding among those not well acquainted with the field. This rebuttal, prepared by the investigators whose works were sited, addresses these inaccuracies so that a fuller and more productive discussion of this area of study ...

Coupling effects in adhesive bonded joints

Composite Structures, 2002
Abstract This paper presents the use of a newly developed unified approach for the analysis and design of adhesive bonded joints that takes into account the effects of asymmetric laminated adherends to study the influence of coupling effects in the adherends of adhesive bonded joints.

Novel Design of a Bonded Lap Joint

AIAA Journal, 2001
A new design of a single-lap joint was proposed and investigated experimentally. In this new design, load eccentricity as well as singular peel stresses in the joint interface were avoided. In fact, numerical calculations show that, in the new design, the peel stress becomes compressive in the joint end region, and the shear load is more evenly ...

Design of bonded joints

Journal of Applied Polymer Science, 1962
AbstractEssentially the entire surface of the U. S. Air Force B‐58 supersonic bomber is aluminum‐bonded panel construction. Primary as well as secondary structural bonded panels were designed and manufactured to operate under demanding service conditions which include high stress, subzero temperature, high temperature, and severe acoustical vibration ...

Analysis of Bonded Joints in Vehicular Structures

AIAA Journal, 1973
Abstract : A linear elastic finite-element analysis is used to evaluate the behavior of an adhesive joint bonding a boron/epoxy composite to a metallic substrate. The adhesive layer is treated as a separate elastic medium of finite thick-ness in order to remove the stress singularity that exists when dissimilar materials are joined.

The Efficient Design of Adhesive Bonded Joints

The Journal of Adhesion, 1975
Abstract A concise method of analysis is used to study the numerous parameters influencing the stress distribution within the adhesive of a single lap joint. The formulation includes transverse shear and normal strain deformations. Both isotropic or anisotropic material systems of similar or dissimilar adherends are analysed.

On the repeatability of the EMI for the monitoring of bonded joints

SPIE Proceedings, 2015
We study the feasibility and the repeatability of the electromechanical impedance (EMI) method for the health monitoring of lightweight bonded joints. The EMI technique exploits the coupling between the displacement field and the potential field of a piezoelectric material, by attaching or embedding a piezoelectric transducer to the structure to be ...

Optimization of bonded joints

AIAA Journal, 1983
A procedure for minimizing the elastic shear stress concentration in adhesive lap joints is presented. The proposed method is based upon tapering the adherends to achieve smooth stiffness transitions and uniform shear stresses. Both single and double lap splices are considered, but numerical examples are restricted to the case of double lap joints ...

Ultrasonic testing of anaerobic bonded joints

Ultrasonics, 2002
The paper deals with ultrasonic testing of adhesive joints between sheets of thickness greater than 1 mm, bonded by a "zero thickness" layer of anaerobic adhesive. In the case of equally thick sheets, interference phenomena can arise that make impossible the use of the "decay method" (a method previously developed by the authors for the case of non ...

Nondestructive testing of adhesively-bonded joints

NDT & E International, 1997
One approach to testing the suitability of an adhesive joint for a particular application is to build and test to destruction a representative sample of the joint. In this way the best adhesive and surface treatment for a given application can be found.
