A plastic stress intensity factor approach to turbine disk structural integrity assessment

A Semi-analytical Approach to Elastic-plastic Stress Analysis of FGM Pressure Vessels

An analytical method for predicting elastic–plastic stress distribution in a cylindrical pressure vessel has been presented. The vessel material was a ceramic/metal functionally graded material, i.e. a particle–reinforcement composite. It was assumed that the material’s plastic deformation follows an isotropic strain-hardening rule based on the von-Mises yield criterion, and that the vessel was...

Application of a Structural Integrity Assessment Software

In this paper, a brief overview is given of two projects concerning structural integrity assessment, including on-line software based on SINTAP procedure. An example of the software usage is presented, and the obtained results are compared with the experimental data and discussed.

Structural integrity monitoring of onshore wind turbine concrete foundations

A new approach to structural integrity assessment based on axial and radial diffusivities.

This study describes a method for performing diffusivity measures along and across a specific direction, derived from white matter in healthy controls. The diffusion tensor (DT) assigns a principal eigenvector (v₁) and eigenvalue (axial diffusivity, d(ax)) to each voxel. The average of the second and third eigenvalues is the radial diffusivity, d(rad) v₁ may be affected by pathology, therefore ...

STRUCTURAL ANALYSIS AND STRUCTURAL OPTIMIZATION OF SELF-SUPPORTING TRUSS TOWERS TO SUPPORT A LARGE WIND TURBINE

This article aims to study the self-supporting truss towers used to support large wind turbines. The goal is to evaluate and validate numerically by finite element method the structural analysis when the lattice structures of the towers of wind turbines are subjected to static loads and these from common usage. With this, it is expected to minimize the cost of transportation and installation of...
