2. Quasi-Static Crushing and Energy Absorption Characteristics of Thin-Walled Cylinders with Geometric Discontinuities of Various Aspect Ratios
Abstract In this paper, energy absorption and deformation capacity of circular thin-walled members with elliptical cut-outs are investigated both numerically and experimentally. Thin-walled members possess the uniform height, thickness, average cross sectional area, material and volume are subjected to axial quasi-static loading. To conduct such tests, speci

12. Parametrization and numerical simulation of the hidrokinetic turbine-otimization using genetics algorithm / Parametrização e simulação numérica da turbina hidrocinética - otimização via algoritmos genéticos
The rotor is the part of the hydrokinetic system whose configuration characteristics are essential due to its influence on the global efficiency of the system. The definition of the blade runner that adapts to the imposed working conditions, increasing the power, is an important factor to be optimized in a hydrokinetic turbine (HKT). In order to make the opt
