  • In this paper the other performance of this method is presented. and the convergence of the method is proven theoretically in .the general case of a harderung body which obeys the elastoplastic process theory. The more complicated 3D problem of bodies of revolution subjected to non-axially symmetric load is investigated.

  • The elastoplastic problem of the half-space with a hole subjected to axially symmetric loading considered in this paper is based on the elastoplastic deformation process theory. Solution of t his problem is carried out by using the modified elastic solution method and the finite element method. Some results of numerical calculation are presented here to give the picture of plastic domains enlarging in the body and t he obtained displacements on the free boundary of the half-space.

  • This paper discusses the dynamic characteristics of an elastically supported Euler-Bernoulli beam subjected to an initially loaded compressive force and a moving point load. The eccentricity of the axial force is taken into consideration. The timehistories for beam deflection and the dynamic magnification factors are computed by using the Galerkin finite element method and the implicit Newmark method.

  • This paper presents a modeling technique t hat derives from t he work of Newmark to describe the behavior of steel-concrete composite beams with elastic shear connection. The model is used to derive expressions for beam curvat ure, rotation and defl ection under monotonic load from wh ich the stiffness matrix is derived and finite element analysis performed on a set of illustrat ive examples. Iviodel results are compared to those obtained using other method.

  • Soils are aggregates of mineral particles, and together with air and/or water in the void spaces, they form three-phase systems. A large portion of the earth’s surface is covered by soils, and they are widely used as construction and foundation materials. Soil mechanics is the branch of engineering that deals with the engineering properties of soils and their behavior under stress.

  • The paper presents a solution based on a detailed analysis of system modeling to assess the stability of the load position during the control under the interplay of factors such as the elasticity of the rope. , weight change as well as other external impacts. Especially based on the actual conditions, analysis and design of automatic load position control system when there is no information about the load location, the main sensor is the sensor that measures the rotation position of the system. Here, lower and feel the pressure to measure the tension of the rope.
