One of the main issues in design foundations is correct forecast development long-term deformations (settlement) foundations. Among factors affecting settlement, one can single out neglect changes rheological parameters soil time and loading regime, as well processes hardening time. The work presents results a study behaviour samples clayey with disturbed structure under conditions triaxial cyc...

The creep problems are often involved in soil under cyclic loading, and its behaviors of loading sparks many arguments current research field. To propose one new model to demonstrate these the was simplified equivalently, elastic-viscoplastic (EVPM) for established based on Bingham model. yield criterion with constant amplitude proposed following load. A constitutive equation EVPM constructed b...

Background and Aim: Oral bacteria can proliferate in the implant-abutment interface (IAI) and cause inflammation in the peri-implant tissues and adjacent bone. This study aimed to assess the effect of zirconia and titanium abutments on the microleakage of the IAI under oblique cyclic loading conditions. Materials and Methods: In this in-vitro study, 12 implant-abutment assemblies with zirconia...

impact is one of the most important subjects which always have been considered in mechanical science. nature of impact is such that which makes its control a hard task. therefore it is required to adopt a safe and secure mechanism for transferring the impact to other vulnerable parts of a structure, when it is necessary. one of the best methods of absorbing impact energy is using thin-walled tu...

In this research, three models of beam-column joint have analyzed under reversed cyclic loading by finite element method using ANSYS software. The first model was designed with a steel-reinforced (longitudinal reinforcement and stirrups), the second performed (GFRP) -reinforced in longitudinal only third (CFRP) only. behaviour loading, their load-storey drift envelope relationship energy dissip...

The main objective of this paper was to study the concrete-to-concrete shear friction behavior under cyclic loading and different test rates. Eight dynamic push-pull tests were performed on concrete specimens with as-cast surface roughness type applying four results include hysteresis loops force-displacement relations. It is concluded that coefficient decreased increased rate. This reduction i...
