Abstract

In this paper an automatic remeshing algorithm of triangular finite elements is presented. It is well known that the element sizes of the mesh play an important role in modeling the continuum, particularly when notable material properties differences exist in contiguous areas of [...]

Abstract

This paper presents advances in recent work of the authors to derive a fractional step scheme based on the stabilized finite element method that allows overcoming the above mentioned problem, resulting in a efficient time accurate scheme.

The starting point is the modified [...]

Abstract

This article presents the first application of the Finite Calculus (FIC) in a Ritz-FEM variational framework. FIC provides a steplength parametrization [...]

Abstract

The paper extends recent work of the authors to include transverse shear effects on rotation-free triangular element for plates (Oñate and Zárate [...]

Abstract

In this paper some results of a wide experimental program are presented and compared with some finite element solution of sheet metal forming problems using a viscous shell formulation.[...]

Abstract

A set of numerical model experiments has been conducted to simulate the circulation driven by oscillatory forcing over a theoretical continental slope configuration used previously in laboratory experiments. The test case considered was the numerical simulation of the flow over [...]

Abstract

This paper summarizes the development for a large displacement formulation of a membrance composed of three-node triangular elements. A formulation in terms [...]

Abstract

Being capable of predicting seakeeping capabilities in the time domain is of great interest for the marine and offshore industry. However, most computer programs used in the industry work in the frequency domain, with the subsequent limitation in the accuracy of their model predictions. [...]

Abstract

This work deals with the simulation of strain localization phenomena through the Strong Discontinuity Approach (SDA) for three dimensional (3D) problems. The main assumptions of this work are the isothermal quasi-static regime, small deformations and rotations, and a material describes [...]

Abstract

This paper investigates the variational formulation and numerical implementation of the damage evolution in solids using the discrete approach of the embedded discontinuity formulation. For this purpose, the ''kinematically optimal symmetric formulation'' (KOS) [...]
