The Effectiveness of PIES Compared to BEM in the Modelling of 3D Polygonal Problems Defined by Navier-Lame Equations
نویسندگان
چکیده
The paper presents the effectiveness of the parametric integral equation system (PIES) in solving 3D boundary problems defined by Navier-Lame equations on the example of the polygonal boundary and in comparison with the boundary element method (BEM). Analysis was performed using the commercial software “BEASY” which bases on the BEM method, whilst in the case of PIES using an authors software. On the basis of two examples the number of data necessary to modeling of the boundary geometry, the number of solved algebraic equations and the stability and accuracy of the obtained numerical results were compared.

The effectiveness of PIES comparing to FEM and BEM for 3D elasticity problems
The paper presents the results of research on the effectiveness of the PIES method developed by the authors, applied to modeling and solving complex 3D problems of elasticity. The results were compared with those obtained using classical element methods FEM and BEM. For the calculation in mentioned methods we have used professional programs ANSYS (FEM), BEASY (BEM) and our own software in the c...
متن کاملStiffeners Mechanical Effect Analysis by Numerical Coupling
Given any structure, we seek to find the solution of mechanical problem as precisely and efficiently as possible. Within this condition, the BEM is robust and promising development, standing out in the analysis of cases with occurrence of large stress gradients, as in problems of fracture mechanics. Moreover, in BEM the modeling of infinite means is performed naturally, without the use of appro...

This paper proposes the use of quadrangular Bézier patches to model and modify the shape of the boundary for linear elasticity problems in 3D. The representation of the boundary in this way derives directly from computer graphics and have been analytically included in developed by the authors parametric integral equation systems (PIES). PIES are the modified classical boundary integral equation...

In the present study, the nonlinear model of non-Newtonian blood flow in cosine-shape stenosed elastic artery is numerically examined. The model is carried out for axisymmetric, two-dimensional and fully developed blood flow. The vessel wall is assumed to be have time-dependent radius that is important factor for study of blood flow. The cosine-shape stenosis convert to rigid artery by using a ...
متن کاملOptimization with the time-dependent Navier-Stokes equations as constraints
In this paper, optimal distributed control of the time-dependent Navier-Stokes equations is considered. The control problem involves the minimization of a measure of the distance between the velocity field and a given target velocity field. A mixed numerical method involving a quasi-Newton algorithm, a novel calculation of the gradients and an inhomogeneous Navier-Stokes solver, to find the opt...
