stability and safety analysis of dams is a subject which has been studied in recent years by several researchers. researchers have used various methods and models for studying the stability of the dam. several methods are proposed for the analysis of earth dams under earthquakes. some of these methods are viscoelastic methods and semi static methods. each of these methods can be used as an appr...

Reasonable determination of the ultimate bearing capacity foundation is great significance in engineering applications. Based on self-developed non-contact testing device for plastic zone shallow foundation, this paper carries out model test research sandy soil and analyzes development law under action load. The main advantages functional characteristics system are that it can realize displacem...

We investigate the behavior of vortex flows in the presence of obstacles using numerical simulations. Specifically, we simulate the evolution of an elliptically loaded vortex sheet in the presence of a stationary flat plate in its path. The plate is represented by a number of point vortices whose strength is such that they cancel the normal fluid velocity on the plate. The sheet is approximated...

Plate anchors are one of the most common types ground used in foundation systems, as they transfer loads from to soil prevent overturning and overcome forces that could threaten integrity structure. The present work concerns study combined effects among behavior anchor plate sandy with without water presence a static state at different head level (h=15, 30, 40 cm) above base for two states impr...

BACKGROUND The locking plates are often used for internal fixation of closed tibial fractures. The use of a locking plate as an external fixator is still controversial, particularly for closed fractures. The purpose of this study is to evaluate the results of external fixation using the femoral less invasive stabilization system (LISS) plate in proximal metaphyseal fractures of the tibia. MET...

The simultaneous effects of soil and existing structures are known as the site-city interaction (structure-soil-structure). The impact of site-city interaction on structure behavior is effective. Thus, this interaction in some regions decreases the responses while increases in other areas. In addition, the site-city interaction of many parameters including the soil type, density rate, height of...

In this study, thermo-nonlocal vibration of double bonded graphene sheet (DBGS) subjected to 2D-magnetic field under biaxial in-plane pre-load are presented. The elastic forces between layers of graphene sheet (GS) are taken into account by Pasternak foundation and the classical plate theory (CLPT) and continuum orthotropic elastic plate are used. The nonlocal theory of Eringen and Maxwell’s re...

In order to study the dynamic response characteristics of circular extended foundation wind turbine in mountainous areas, a 1:10 scaled model test was carried out on 2MW turbine, and deformation under random load were analyzed by ABAQUS numerical calculation. The results show that: (1) has different stress types windward side leeward side. components are subjected tensile stress, while compress...

In the present study, the dynamic buckling of the graphene sheet coupled by a viscoelastic matrix was studied. In light of the simplicity of Eringen's non-local continuum theory to considering the nanoscale influences, this theory was employed. Equations of motion and boundary conditions were obtained using Mindlin plate theory by taking nonlinear strains of von Kármán and Hamilton's principle ...
