Laboratory Investigation on Reactivated Residual Strength

Journal of Geotechnical and Geoenvironmental Engineering - ASCE, 2008
Recent research has outlined that mobilized in situ strength at the reactivation of displacements along a preexisting sliding surface may be slightly greater than laboratory residual strength. Although geotechnical literature explains this difference in various ways — for instance, strength gain due to soil aging — little work has been devoted to this ...

Residual Stresses and Strength of Hard Chromium Coatings

Materials Science Forum, 2011
Experimental and numerical investigations have been performed on the relationships between coating parameters, residual stresses, micro-cracks and the near surface strength of electrochemically deposited hard chromium coatings. The experimental investigations included: X-ray measurements of residual and externally-applied stresses; crack density ...

Residual debris and bond strength—Is there a relationship?

American Journal of Orthodontics and Dentofacial Orthopedics, 1988
A study was undertaken to test the theory that there is a relationship between bond strength at the separate interfaces of the direct bonding system and the amount of residual debris remaining on the enamel surface following removal of a bonded appliance. In separate experiments, shear loads were applied at the complete direct bonding system and at the

Residual strength and toughness of damaged composites

Journal of Materials Science, 1990
A study has been made of the effect of prior damage on the tensile strength and toughness of a number of carbon and glass fibre reinforced plastics materials. This prior damage was introduced by tension fatigue cycling, by transverse compression, by repeated impact, and by stress corrosion.

Drained Residual Strength for Landslides

GeoFlorida 2010, 2010
Drained residual shear strength is considered applicable for the analysis of slopes with a preexisting shear surface. Torsional ring and direct shear tests were performed to investigate the gain in strength, if any, along a preexisting shear surface with time.

Residual strength of maraging steel

Journal of Materials Science, 1989
Surface crack tension (SCT) specimens of 18 Ni 1800 MPa grade maraging steel (parent metal and welded) were used to evaluate the residual strength in 0.015 and 0.03m wide panels. For 0.03 m wide panels which satisfy infinite plate condition up to 0.006 m surface crack length, the residual strength variation between minimum and maximum crack sizes lie ...

Residual Shear Strength

Journal of the Soil Mechanics and Foundations Division, 1970
AN EXPLANATION IS GIVEN FOR THE DEPENDENCE OF THE RESIDUAL ANGLE OF INTERNAL FRICTION OF SOIL ON CLAY CONTENT. ONCE RESIDUAL CONDITIONS ARE ATTAINED, THE SOIL IS SEPARATED BY A FAILURE PLANE INTO TWO RIGID BLOCKS THAT SLIDE OVER ONE ANOTHER. IF C IS THE CLAY FRACTION DEFINED AS THE VOLUME OF CLAY DIVIDED BY THE VOLUME OF SOLIDS, THEN AS A FIRST ...

The Residual Strength of Confined Concrete

Advances in Structural Engineering, 2010
Structural engineers have long recognised the importance of member ductility in the design of reinforced concrete members to overcome uncertainties in the design procedure as well as in absorbing energy due to dynamic loads such as earthquakes, impact and blast loads. This has lead to much research on quantifying the rotational capacities of reinforced
