Safety analysis using finite elements
TL;DR: In this paper, a finite element based method for determining safety factors is described, where the stress field produced by finite element analysis is used in conjunction with a conventional limit method to determine the safety factor.

A 3-D streamline tracking algorithm using dual stream functions
TL;DR: A methodology has been developed for constructing streamlines and particle paths in numerically generated fluid velocity fields using a graphical technique to convert the discretely defined flow within a cell into one represented by two three-dimensional stream functions.

An interface damage model that captures crack propagation at the microscale in cortical bone using XFEM.
TL;DR: A model for crack propagation in 2D at the microscale in cortical bone was developed using the extended finite element method by combining the maximum principal strain criterion with an additional interface damage formulation in the cement line to capture crack deflections at the osteon boundaries as observed in experiments.

New Approach to Determine Three-Dimensional Contacts in Blocks System: Penetration Edges Method
TL;DR: The limitation of the c-p method for 3D distinct element analysis is discussed in this paper, where the authors proposed a new approach which is simple to implement and can overcome the limitation of this method.

TL;DR: It will be possible to compute data for arbitrary polygons, for instance administrative units which do not exist any longer, by assigning real estate data to the central points by means of a special program.
