Minimum energy based interpolation for interactive incremental well‐path design

Kailash Jha

In this work, minimum energy based interpolation has been done for an optimal well path and effects of energy and fitting coefficients have been studied. An optimal well path also…

Transient dynamic analysis of dam‐reservoir interaction by coupling DRBEM and FEM

Semih Küçükarslan, Safa B. Coşkun

In this paper, time domain dynamic analysis of dam‐reservoir interaction is presented by coupling the dual reciprocity boundary element method in the infinite fluid domain and the…

Stable analysis of long duration motions of FE‐discretized structures in central force fields

Burkhard Göttlicher, Karl Schweizerhof

The computation of structures moving in central force fields generally requires long‐time integration including geometrically nonlinear behavior (large rotations) as such, e.g…

Stability results for two classes of linear time‐delay and hybrid systems

M. De la Sen, C.F. Alastruey

The stability of linear time‐delay systems with point internal delays is difficult to deal with in practice because of the fact that their characteristic equation is usually of…

A procedural approach of inspecting CAD model errors

Jeongsam Yang

Neutral format translators such as STEP and IGES have been used to exchange CAD model between the various CAD systems in the product development process. But imperfect…

Assessing maximum possible damage for contaminant release events

Fernando Camelli, Rainald Löhner

The combined use of damage criteria, genetic algorithms and advanced CFD solvers provides an effective strategy to identify locations of releases that produce maximum damage. The…

Closed form solution of optimal design of rectangular reinforced concrete sections

M.H.F.M. Barros, A.F.M. Barros, C.A. Ferreira

The aim of this paper is to obtain the analytical solution for the optimal design of reinforced concrete sections under ultimate design. The equilibrium equations of the section…

Computation of weakly‐compressible highly‐viscous liquid flows

M.F. Webster, I.J. Keshtiban, F. Belblidia

We introduce a second‐order accurate time‐marching pressure‐correction algorithm to accommodate weakly‐compressible highly‐viscous liquid flows at low Mach number. As the…
