Strength and Efficiency during Lap Joining Molding of GMT-sheet

Volumetrical Characterization of Sheet Molding Compounds

For a comprehensive study of Sheet Molding Compound (SMC) surfaces, topographical data obtained by chromatic confocal imaging were submitted systematically for the development of a profile model to understand the formation of cavities on the surface. In order to qualify SMC surfaces and to predict their coatability, a characterization of cavities is applied. To quantify the effect of surface mo...

Residual Strength Analyses of Riveted Lap-Splice Joints

Aging aircraft may develop multiple-site damage (MSD) that can reduce the structural integrity of fuselage structures. The existence of small cracks emanating from adjacent rivet holes in a fuselage lap-splice joint is of major concern. Small collinear cracks greatly reduce the residual strength of a panel with a lead crack. Recent studies predicting the residual strength of flat and curvilinea...

Application of Finite Element Analysis in Sheet Material Joining

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

EFFECTS OF pH ON LAP-SHEAR STRENGTH FOR ASPEN VENEER

This study is one part of a whole project called “Impact of Extreme pH of Structural Adhesives on Bond Durability.” The objective of this study was to evaluate effects of pH on wood– adhesive bond strength and chemical change in aspen (Populus tremuloides Michx) wood caused by extreme pH exposures. Aspen veneer lap-shear samples were tested for maximum stress (N/mm) and wood failure (%) after e...
