Abstract Delamination is considered as one of the most critical failure modes which occurs near free edges in laminated composites due to high interlaminar stress. When classical plate theory used determine plane stress, stresses cannot be assessed by this theory, it adopts stress assumption. For that, a three-dimensional finite element analysis adopted calculate in-plane well out-of-plane unde...

In this paper, a room acoustics simulation using a finite difference approximation on a face-centered cubic (FCC) grid with finite volume impedance boundary conditions is presented. The finite difference scheme is accelerated on an Nvidia Tesla K20 graphics processing unit (GPU) using the CUDA programming language. A performance comparison is made between 27-point finite difference schemes on a...

Using inverse positivity properties and Brouwer’s fixed point theorem, we derive existence and uniqueness results for certain nonlinear systems of equations with off diagonal nonlinearity. The type of systems considered arises from stable finite volume discretizations of viscous nonlinear conservation laws and has a wide range of applications.
