Fast search algorithms for look‐up tables

Sugjoon Yoon, Hyunjoo Kang

Various parameter values are provided in the form of data tables, where data keys are ordered and unevenly spaced in general, for real‐time simulation of dynamic systems. However…

Finite strain endochronic plasticity with reference to metal tube under torsion

A.R. Khoei, A. Bakhshiani, M. Mofid

In this paper, a new rate type endochronic constitutive model is introduced to describe deformations in the finite strain range. A new material dependent objective rate of Cauchy…

Elasto‐plastic analysis of three‐dimensional structures

M. Rezaiee‐Pajand, M.R. Nazem

In this paper, quasi‐Tresca yield surfaces are reviewed. In order to do elasto‐plastic analysis, a new yield criterion is presented. The proposed yield surface can be used in…

Dynamic T‐search for accelerating searching speeds in Delaunay triangulation

Sugjoon Yoon

For realistic simulation of off‐road vehicles terrain surfaces have to be modeled in detail, and wheel‐surface contacting geometry must be well defined in order to obtain proper…

Mesh tying on curved interfaces in 3D

Michael A. Puso, Tod A. Laursen

In this work, a mortar method is implemented for tying arbitrary dissimilar 3D meshes, i.e. 3D meshes with curved, non‐matching interfaces. The 3D method requires approximations…

A comparison study of the convergence characteristics and robustness for four variants of SIMPLE‐family at fine grids

M. Zeng, W.Q. Tao

A comparative study is performed to reveal the convergence characteristics and the robustness of four variants in the semi‐implicit method for pressure‐linked equations…
