Simulation of solutions to protect reinforced concrete structures under

The paper aim to assess the fracture failure mode of reinforced concrete components under contact blast loading using both on site experiment and numerical simulation. From there, we propose a solution to protect reinforced concrete components under explosive load contact. Based on the results, the selection of computational models, constitutive laws of the material in the simulation of the structure under the impact of blast loading in the ABAQUS program has been evaluated.

Calculation of Characteristics Describing the Properties of Dynamical Systems

Abstract There are characteristics that uniquely define the properties of dynamical systems from the point of its dynamical response. For example, natural frequencies and natural modes or frequency response functions can be assigned to these characteristics. Determination of these characteristics is fixed on the selection of computational model and on the means of structure excitation. This contribution discusses about analysis of such characteristics.

Numerical Simulation of Coal Suspension Sedimentation

Abstract The article describes the feasibility of numerical simulation of sedimentation process of coal suspension, with high concentration, using the Ansys Fluent package, with the assumption monodisperse grain composition of the disperse phase of the suspension. The analysis contains selection of computational model, determine the parameters for analysis and comparison of the results with laboratory tests. To comparison laboratory measurement and numerical simulation sedimentation test was used. In the analysis was used suspension from the coal purification process.
