background: the aim of this study was to compare the shear bond strength of four one-step self-etch adhesives with different ph values to enamel and dentin. materials and methods: in this in vitro study, 200 bovine permanent mandibular incisors were used. four one-step self-etch adhesives with different ph values were tested both on enamel and on dentin: adper™ easy bond self-etch adhesive (ph ...

A continuum-based finite-element methodology is established for quantifying the stability of earthen embankments built on saturated soil deposits. Within the methodology the soil is treated as a fluid-solid porous medium, in which the soil skeleton’s constitutive behavior is modeled using a smooth elastoplastic cap model that features continuous coupling between deviatoric and volumetric plasti...

the mechanical behaviour of rockfill materials and aggregates depends not only on particle size and compaction, but also on their strength and lithological properties. in this research two types of large triaxial and direct shear tests are performed on rockfill materials. this paper compares the stress-strain behaviour of sandstone and andesibasalt materials in triaxial compression tests (3006...

Shear strength is the essential engineering property of soil required to analyze and design foundations, retaining walls, bridges, embankment, related infrastructure. The laboratory equipment field instruments are not sufficient in developing countries obtain properties, especially properties. Thus, Geotechnical engineers usually endeavor develop statistical models that best fit a particular ar...

In geotechnical engineering applications, it is very important to obtain the undrained shear strength of remolded soils accurately and reliably. This study aims a trustworthy solution determine clay mixtures using Atterberg limit test results in various states consistency. An experimental was carried out involving wide range varying plasticity geological origin. analyses, variation soil dependi...
