چکیده

A numerically efficient approach for the prediction of consecutive growth of delaminations with curved fronts is developed. The approach is based on the assumption that the delamination grows from its current front to a predefined advanced front and that the delamination front remains smooth during the entire growth process. For computation of the load required to propagate the delamination the finite element method and the virtual crack closure technique are employed and incremental growth is predicted. As an example, delamination growth in a laminated plate is analyzed.

Performance Evaluation of a Curved Type Vane Separator at Different Plate Spacings in the Range of 25 to 35mm Using Numerical Simulation

In this paper, the turbulent air droplet flow inside a single passage of a curved type vane separator has been studied numerically. The simulation is based on the Eulerian - Lagrangian method. For turbulent air flow calculations, a computer code was developed to solve the Reynolds Averaged Navier Stokes (RANS) equations together with the equations of Reynolds Stress Transport Model (RSTM) o...

Implementation of D3Q19 Lattice Boltzmann Method with a Curved Wall Boundary Condition for Simulation of Practical Flow Problems

In this paper, implementation of an extended form of a no-slip wall boundary condition is presented for the three-dimensional (3-D) lattice Boltzmann method (LBM) for solving the incompressible fluid flows with complex geometries. The boundary condition is based on the off-lattice scheme with a polynomial interpolation which is used to reconstruct the curved or irregular wall boundary on the ne...

Numerical study of flow of labyrinth weir with triangular and curved plan form using Fluent software

Labyrinth weirs have not a straight crest in the perpendicular direction to the flow. The plan view of the weir consists of multiple and broken linear crests that cause the increase of its effective length. The advantages of this type of weirs are higher discharge capacity, easy aeration as well as low fluctuations of water surface at the weir upstream. This paper deals with the simulation of t...

Buckling of Laminates with Multiple Through-the-Width Delaminations Using Spring Simulation Model

Delamination is one of the most common failure modes in composite structures. In particular, when the laminated composites are subjected to compressive loads, delamination becomes a constraint in the design process. In this study, the system is modeled as a plate supported by an elastic foundation. The elastic adhesive layer between the buckled sublaminates is represented by some parallel sprin...
