An adhesive is a material used for holding two surfaces together. An adhesive must wet the surfaces, hold fast to the surfaces, develop strength after it has been applied, and remain Stable. In this work we work on aerospace application, for that application we used material as SS304 and used Adhesive as EA-E30HV.We used specimen size as 130*30*1.95mm. We used different overlap length and overl...

Finite elemen model for the structural behaviours of bi-directional (2D) FG porous microbeams based on a quasi-3D theory and modified strain gradient (MSGT) is presented. As main novelty this study, in order to capture accurately size effects, MSGT employed with three material length scale parameters (MLSPs) rather than modifed couple stress (MCST) only one MLSP. The properties including MLSPs ...

The scaling properties of a post-mortem mortar crack surface are investigated. The root mean square of the height fluctuations is found to obey anomalous scaling properties, but with three exponents, two of them characterizing the local roughness ( zeta approximately 0.79 and zetae approximately 0.41 ) and the third one driving the global roughness (zetag approximately 1.60) . The critical expo...

a relationship based on the modified couple stress theory is developed to investigate the flexural sensitivity of an atomic force microscope (afm) with assembled cantilever probe (acp). this acp comprises a horizontal cantilever, two vertical extensions and two tips located at the free ends of the extensions which form a caliper. an approximate solution to the flexural vibration problem is obta...

local scour around the abutment is of utmost importance in bridge failures. numerous methods such as riprap have been proposed to reduce the destructive effects of scouring; one of the ways to harness and reduce the local scour depth is installed protective collars around the abutment. in this paper effect of collar elevation (upper level, bed level and lower level), collar geometry and its siz...
