Analysis of fluid-structure interaction of a torus subjected to wind loads
Journal Title: Computer Assisted Methods in Engineering and Science - Year 2014, Vol 21, Issue 2
Abstract
In the paper the aerodynamic forces acting on a part of a water slide or other object with curved, tubular shape, depending on the section of a torus and value of the wind velocity, were obtained. This was done by means of finite element method (FEM) and finite volume method (FVM) computer simulations, using modules: computational fluid dynamics (CFD) and fluid-structure interaction (FSI) and taking into account the Eurocode EN 1991-1-4.

SVD as a preconditioner in nonlinear optimization
Finding a solution of nonlinear constrained optimization problem may be very computer resources consuming, regardless of solution method adopted. A conceptually simple preconditioning procedure, based on singular value d...
Improved two-dimensional cracked finite element for crack fault diagnosis
In this paper the two-dimensional finite element with an embedded edge crack proposed by Potirniche et al. (2008) is improved further for crack depth ratios ranging up to 0.9 and for predicting the natural frequency of a...
