Magnetic pressure stressing of lap joints: Modeling and experimental verification
Journal of Nondestructive Evaluation, 1997A novel electromagnetic stressing/optical detection method has been developed in response to the need for better nondestructive evaluation techniques for the detection of disbonds in aging aircraft lap joints. This technique uses magnetic pressure to pull the top surface of a thin conductive bonded sheet and senses the out-of-plane displacement of the ...

As already said earlier, a primary loading for the fuselage skin is hoop tension. However, the total effect of pressurization is a combination of hoop and longitudinal tension and local out-of-plane bending of the skin, the so-called pillowing. Besides the circumferential pillowing between the stiffeners shown in Fig. 2.1a, pressurization also causes a

Instantaneous Energy Dissipation Rate in a Lap Joint—Uniform Clamping Pressure
Journal of Applied Mechanics, 1968Equations are derived for the load/deflection relations, the energy dissipation per cycle, and the instantaneous rate of dissipation. The energy dissipation per cycle is only valid for steady-state cyclic loading, whereas the load/deflection equations and instantaneous dissipation rate are valid for arbitrary loading and take into account the previous ...

The Journal of Prosthetic Dentistry, 2010
Achieving an optimal esthetic result when replacing missing teeth with implant-supported restorations in the esthetic zone is a demanding surgical and restorative challenge. This clinical report describes the use of a cantilevered, cemented, implant-supported restoration with gingiva-colored ceramics and a circumferential pressure-ridge lap pontic to ...

An Analytical Solution for Calculating Stresses on Lap Patches Used on Pipes and Pressure Vessels
Volume 3: Design and Analysis, 2008Lap patch repairs are used regularly in petrochemical industries as temporary repairs for short term operations. In this paper a simple methodology is proposed on how to calculate the stresses on a lap patch using simple analytical approximation.

Application of pressure-sensitive adhesive systems in laser-beam welding of lap joints
ICALEO 2009: 28th International Congress on Laser Materials Processing, Laser Microprocessing and Nanomanufacturing, 2009This paper presents a hybrid joining technology where joining partners have been preassembled by means of pressure-sensitive adhesive and subsequently laser-beam welded on lap joint. This simple and innovative hybrid technology promises a reduction of the production costs by minimizing the clamping complexity.

Effect of Cure Temperature and Pressure on Autoclave-Bonded Polycarbonate Single Lap Joints
Volume 2: Advanced Manufacturing, 2016This study investigates the effect of cure temperature and pressure on the mechanical performance of autoclave-bonded single lap joints (SLJ). Joint load transfer capacity (LTC) and failure mode analysis are provided. Test joints are made of two polycarbonate lexan adherends that are autoclave-bonded together using aliphatic polyether (Polyurethane ...

Plastic Collapse at Lap Joints in Pressurized Cylinders under Axial Load
Journal of Structural Engineering, 1994Circular steel silos and tanks are often constructed from rolled-steel plates with welded or bolted lap splices. Where the lap runs horizontally around the silo circumference, the lap connection causes a local eccentricity in the line of vertical thrust in the shell wall.
