Dynamic Crack Propagation in Composite Structuresof a finite element formulation based on a plane stress behavior, whereas the crack growth is predicted by a Fracture Mechanics approach. In order to simulate the dynamic crack growth, the proposed modeling utilizes a fracture toughness criterion based on the energy release rate (ERR) and the corres

Numerical Modeling of Complex Structures: Shells and Biological Cellsnt of mathematical model of biological cells based on homogenization techniques. In the first part, we present a finite element formulation which describes a refined shell theory in a natural and simple way using curvilinear coordinates. The first-order shell theory with seven parameters is derived

Free Vibration Characteristics of Thermally Loaded Cylindrical Shellg conditions. Therefore, the free vibration characteristic of a thermally loaded cylindrical shell was analyzed in this study. ABAQUS was used for the analysis and a thermo-elastic experimental modal test was conducted. Configuration of the shell is 5 m long, 0.4 m diameter, 0.002 m thick and its ma

Model of Large Displacements in Static Analysis of Shelled. Degenerated curved shell elements were used. The presented numerical model was verified on the results of three experimentally tested very slender steel structures, with elastic behaviour of material for all applied loads.

Nonlinear Time-Dependent Analysis of Prestressed Concrete Shells simulates the dominant nonlinear effects of concrete: the creep, shrinkage and aging, the development of cracks in tension and yielding in compression, and the changes in the tensile and shear stiffness in cracking zones. Reinforcing steel is modelled as a separate layer with anisotropic material p

DBEM and FEM Analysis of an Extrusion Press Fatigue Failurender of an extrusion press for aluminum sections. The crack initiates at the inner surface of the cylinder and propagates through the thickness causing a leakage of the pressurized oil and consequent production stop. The fatigue load is induced by the pressure variation inside the cylinder as needed
