Application of Discrete Crack in Nonlinear Dynamic Analysis of Shahid Rajaee Arch Dam
(Materials and Energy Research Center, 2001-02-01)the nonlinear discrete crack modeling of Shahid Rajaee thin arch dam is considered. The interface elements are positioned such that certain potential separated blocks can form possible failure mechanisms. The dynamic ...

Comaprison of Mass-Transfer Efficiencies of Scc and Structured Packing
(Materials and Energy Research Center, 2001-02-01)In a previous paper, pressure drop, flooding and mass-transfer characteristics of a novel pilot-scale distillation column called spinning cone column (SCC) were presented. Here, we present the result of comparison of ...

Estimation of Hydrodynamic Force on Rough Circular Cylinders in Random Waves and Currents (RESEARCH NOTE)
(Materials and Energy Research Center, 2001-02-01)Most of the Codes of Practice (API, BSI, DnV, NPD) uses Morison's equation to estimate hydrodynamic loads on fixed and moving offshore structures. The significant difference in the prediction of the loads mainly arises ...
