A prestressing procedure is proposed for reduction of stress concentrations at the leading edges of adhesive bondlines in composite skin/ ange assemblies. A Ž niteelementanalysisof a speciŽ c geometryof such an assembly is presented,whichaccounts for nonlinear viscoelastic deformation of the adhesive. Design diagrams based on elastic analysis are constructed for evaluation of prestress forces ...

The measurement of damage constants in adhesive bonding has been investigated. Bulk adhesive was used in this study for two reasons: a) stress distribution in bulk adhesive is simpler than adhesive in joints and b) specimen dimensions met fatigue test standard. Bulk adhesive was made from film-form of epoxy resin. In general, the characteristics and the behaviour of bulk adhesive may differ fro...

BACKGROUND & OBJECTIVE Adhesive capsulitis of the shoulder is a condition of unknown aetiology that results in the development of restricted active and passive glenohumeral motion. It has been reported that magnetic resonance (MR) imaging is useful in diagnosing adhesive capsulitis. We carried out this study to assess how pain and/or resistance during contrast material injection affects the dia...

BACKGROUND AND PURPOSE The purpose of this case report is to describe the use of end-range mobilization techniques in the management of patients with adhesive capsulitis. CASE DESCRIPTION Four men and 3 women (mean age=50.2 years, SD=6.0, range=41-65) with adhesive capsulitis of the glenohumeral joint (mean disease duration=8.4 months, SD=3.3, range=3-12) were treated with end-range mobilizat...

Phragmatopoma Californica builds a tubular dwelling by gluing bits of sand and seashell together underwater with a proteinaceous adhesive. In the lab, the animals will build with 0.5 mm glass beads. Two spots of glue with a consistent volume of about 100 pL each are deposited on the glass beads before placement on the end of the tube. The animals wriggled the particles for 20-30 s before lettin...

Abstract The need to manufacture lightweight structures from ultra-high-strength steels is forcing industry look for new joining technologies. Hybrid joints are one of the ways join materials. This paper investigates ultra-high strength steel plates using laser welding and adhesive bonding. Steel used in this was abrasion resistant (AR600) with tensile (Rm) ≥ 2 GPa. Three different epoxy adhesi...

STUDY DESIGN Randomized clinical trial. OBJECTIVE To compare the effectiveness of anterior versus posterior glide mobilization techniques for improving shoulder external rotation range of motion (ROM) in patients with adhesive capsulitis. BACKGROUND Physical therapists use joint mobilization techniques to treat motion impairments in patients with adhesive capsulitis. However, opinions of th...

Abstract Bond line openings while an adhesive is still viscous (liquid or paste-like) leave characteristic marks. Air fingers and cavitation develop on the surface of when joint parts are fully partially separated before solidifying adhesive. Therefore, observation air provides important clues root cause failure bond lines. There limited knowledge about factors that lead to formation either cav...
