Based on the hypothesis that shearing stresses and normal tensile stresses both play a decisive role in fracturing and brittle failure of rock material, a novel strength criterion was developed in one of the earlier works of the author. In the criterion, a certain parameter ν' occurs which depends on the structure of the material. Originally, the parameter was treated as a constant, which resul...

Clinching technologies are increasingly used to join sheet materials in manufacturing, especially automotive lightweight applications. However, clinched joints have a weak static strength and high protuberance, which influence the application of clinching technology. In order improve decrease protuberance joint, new method aluminum alloy with two-stroke flattening (TFC) was investigated this pa...

A new hybrid atomistic-coarse-grained (HACG) treatment of reversible processes in multiple-scale systems involving fluid-solid interfaces was tested through isothermal-isobaric Monte Carlo simulations of the quasistatic shearing of a model two-dimensional lubricated contact comprising two planar Lennard-Jones solid substrates that sandwich a softer Lennard-Jones film. Shear-stress profiles (plo...

AIMS/BACKGROUND To clarify whether intraocular lens (IOL) implantation in the human eye affects the durability of polymethylmethacrylate over an average period of 10.9 years. METHODS Shearing stress and extent of damage following neodymium (Nd):YAG laser application to 18 study and 12 control optics were examined. RESULTS No significant difference was found between the study and the control...

OBJECTIVES The present study was conducted to evaluate the optimal method of enhancing the bond strength of a composite resin to the facial surface of the primary anterior stainless steel crowns using various surface treatments namely Nd: YAG laser surface treatment, sandblasting , alloy primer application and no surface treatment. STUDY DESIGN The study sample consisted of 60 primary anterio...

Soil exists mainly in unsaturated conditions. Therefore, accurate prediction of the soil shear strength for conditions also becomes equally important geotechnical design earth structures. This study primarily investigates effect moisture content on its strength. The characteristics silica sands with different grain sizes were studied using modified triaxial apparatus and analytical methods. For...

Mechanical properties of hydrate-bearing sediments (HBS) are crucial for evaluating drilling- and production-induced geo-hazards. However, investigations on mechanical behaviors clayey-silt samples containing hydrate insufficient due to low efficiency in preparing reconstituted samples. Herein, we carried out a series triaxial shear tests analyze the deformation tetrahydrofuran (THF) hydrate. T...
