Shielding Design

In this paper we present an even parity approach for deriving the detector response flux. Forward and adjoint angular fluxes, ψ(r,Ω) and ψ†(r,Ω) obtained from the K+[ψ+] and K†+[ψ†+] variational principles are used to determine the spatial channels in shielding materials. These spatial channels clearly show the dose rate passages from the source to the detecting point, hence weak and strong points of the shielding design is illustrated thereafter. Spatial and angular components of the fluxes are approximated using the finite element method (FEM) as well as the spherical harmonics polynomials (SHP), respectively. By the adjoint weighted even parity flux, we can obtain the multigroup response fluxes over arbitrary shaped multidimensional geometries with less computational efforts compared to full parity approaches. A number of test are examined via the code ENTRANS, developed for Even parity Neutron TRANSport calculations. Results confirm ability and robustness of the proposed approach.

Element Simulation

The finite element modeling is established for reinforced concrete(RC) beam reinforced with fiber reinforced polymer (FRP) using the serial/parallel mixing theory. The mixture algorithm of serial/parallel rule is studied based on the finite element method. The results obtained from the finite element simulation are compared with the experimental data. The comparisons are made for load-deflection curves at mid-span. The numerical analysis results agree well with the experimental results. Numerical results indicate that the proposed procedure is validity.

The finite element method is used to study stresses in two types of spherical pressure vessel heads having very wide range of applications in industries. The first problem involves a nozzle to sphere intersection reinforced by a pad and subjected to radial thrust load. The second problem deals with a pressurized thick hemispherical drumhead with a circular manhole. These structures are modeled using eight-node axisymmetric solid of revolution finite elements. Numerical values of circumferential and meridional stresses from the present analysis show excellent agreement with experimental data from the literature.

Continuously Cast

This paper presents approaches to the computational analysis of solidification and cooling processes of continuously cast billets in order to improve and develop technological modes in the conditions of modern continuous casting machines using FEM.The application of modern numerical methods for solidification and cooling of workpieces on continuous casting machines is considered. The use of the finite element method is justified when using computational and experimental data for the development and improvement of casting technology.
