thermal cycling, analysis of separate, sequential and concurrent EM and thermal cycling (TC) was imposed on single shear lap joints
, and the microstructure and crystal orientations were incrementally characterized using electron backscatter diffraction (EBSD) mapping.
Then single lap joints
with neat adhesive and adhesive-RGO mixture were produced.
In the second run, single lap joints
were produced, after laser treatment, to measure the effect of the treatments on the adhesive strength.
Furthermore, per SCVWD standard design philosophy for reliability and protection of the public water supply, the field joints were all bell and spigot welded lap joints
Occurs in crevices created by rubber seals, gaskets, bolt heads, lap joints
, dirt or other surface deposits.
Upright cuts--for lap joints
, tenons or rabbets--aren't a good job for a table saw.
The topics include stress and strain analysis of symmetric composite single lap joints
under combined tension and in-plane shear loading, modeling cylindrical joints with a functionally graded adhesive interlayer, testing dual adhesive ceramic-metal joints for aerospace applications, modeling composite sandwich T-joints under tension and bending, and detecting interface failure in adhesively bonded composite joints using a novel vibration-based approach.

RIVETED LAP JOINTS
IN AIRCRAFT FUSELAGE: DESIGN, ANALYSIS, AND PROPERTIES (SOLID MECHANICS AND ITS APPLICATIONS).
FTFCs are fogged into the airframe in a uniform mist, settling on all the interior surfaces, and then flowing into small spaces, between skins and ribs, between lap joints
and even along rivet shanks.
A senior Boeing engineer said this month that the company normally did not expect that airlines would need to inspect the lap joints
for metal fatigue until an aircraft had completed about 60,000 flights.
Although examining lap joints
is nothing new, inspectors have never utilized advanced monitoring tools since they considered that part of the plane impervious to cracks.
