Stochastic finite element: a non intrusive approach by regression

Slope reliability analysis considering spatially variable shear strength parameters using a non-intrusive stochastic finite element method

Uncertainty Propagation Using a Stochastic Finite Element Approach

The present study focuses on the development of a general framework for propagating the effects of parametric uncertainty, modeled as random fields, from input to output for complex engineering systems via Stochastic Finite Element techniques. These techniques are similar in concept to deterministic finite element approaches in that they approximate both input and output quantities in terms of ...

Analysis of three-dimensional fracture mechanics problems: A non-intrusive approach using a generalized finite element method

This paper shows that the generalized finite element method with global–local enrichment functions (GFEM) can be implemented non-intrusively in existing closed-source FEM software as an add-on module. The GFEM is based on the solution of interdependent global (structural) and local (crack) scale problems. In the approach presented here, an initial global scale problem is solved by a commercial ...

Finite Element Stochastic Analysis

Numerical models can be valuable tools in the prediction of seepage. The results can often be misleading if proper variational analysis is not performed. Measurement of the soil-water characteristic curve (SWCC) or saturated and unsaturated hydraulic conductivity information is often neglected or minimized. The modeller is therefore forced to develop a seepage model based on estimated soil prop...

A hierarchical non-intrusive algorithm for the generalized finite element method

An algorithm for non-intrusively coupling a commercial finite element software with a research code implementing a hierarchical enrichment of finite element spaces is presented. Examples of hierarchical methods supported by the algorithm are the Generalized or eXtended FEM (GFEM), the scale-bridging GFEM with numerically defined enrichment functions (GFEMgl), and the p-version of the FEM. The p...
