In this section, the finite element equations for the updated Lagrangian formulation are developed by means of the principle of virtual power. For this purpose the current domain Ω is subdivided into elements Ω e so that the union of the elements comprises the total domain, Ω = ∪ Ω e . The nodal coordinates in the current configuration are denoted by x

Discrete-Element Interferometers
2010A number of Long Baseline Optical Interferometers (LBOI), providing submilliarcsec resolution, are in place on Earth, while space-based telescope arrays are being designed (Saha 2002; Monnier 2003; Labeyrie et al. 2006). Most of these instruments combine the features of the Michelson design and the radio interferometers.

Discrete‐element modelling of detachment folding
Basin Research, 2005ABSTRACTA two‐dimensional, discrete‐element modelling technique is used to investigate the initiation and growth of detachment folds in sedimentary rocks above a weak décollement level. The model depicts the sedimentary rocks as an assemblage of spheres that obey Newton's equations of motion and that interact with elastic forces under the influence of ...

Discrete Morphology with Line Structuring Elements
2003Discrete morphological operations with line segments are notoriously hard to implement. In this paper we study different possible implementations of the line structuring element, compare them, and examine their rotation and translation invariance in the continuous domain.

Discretization with Finite Elements
1984Here we deal with the numerical solution of optimum design problems using computers. Of the three numerical methods for solving elliptic partial differential equations, the finite element method (FEM) is the obvious one to choose to use when the domains are the unknowns.
