An object-oriented class design for the generalized finite element method programming
Autor: Dorival Piedade Neto, Manoel Dênis Costa Ferreira, Sergio Persival Baroncini Proença
Publikováno v: Latin American Journal of Solids and Structures, Vol 10, Iss 6, Pp 1267-1291
The Generalized Finite Element Method (GFEM) is a numerical method based on the Finite Element Method (FEM), presenting as its main feature the possibility of improving the solution by means of local enrichment functions. In spite of its advantages,

The Splitting Method and the GFEMin the Two-Dimensional Analysis of Linear Elastic Domains with Multiple Cracks
Autor: Igor Frederico Stoianov Cotta, Sergio Persival Baroncini Proença
Publikováno v: Latin American Journal of Solids and Structures, Vol 13, Iss 14, Pp 2573-2605
Abstract The aim of this paper is to analyse two-dimensional linear elastic continuum containing multiple interacting cracks. Both the mechanical model and the numerical approach are addressed throughout the text as key concepts for the computational

Isotropic yield surfaces for porous ductile materials: complete geometric representation by a computational homogenisation procedure
Autor: Wanderson Ferreira dos Santos, Ayrton Ribeiro Ferreira, Sergio Persival Baroncini Proença
Publikováno v: Engineering Computations.
PurposeThe present paper aims to explore a computational homogenisation procedure to investigate the full geometric representation of yield surfaces for isotropic porous ductile media. The effects of cell morphology and imposed boundary conditions ar

It is assumed in this paper that energy dissipation is a two-phase phenomenon. During the pre-localization stage, dissipation is a continuous process. After localization, it is lumped in surfaces of zero volume. To describe this process, it is propos

The extended lumped damage mechanics: A new formulation for the analysis of softening with FE size-independence
Autor: David Leonardo Nascimento de Figueiredo Amorim, D. Piedade Neto, Julio Flórez-López, Sergio Persival Baroncini Proença
Publikováno v: Mechanics Research Communications. 91:13-18
This paper presents a finite element formulation for the analysis of softening in plane problems. The model is not based on the non-local or gradient-dependent approaches. It is an extension of lumped damage mechanics. Lumped damage mechanics, or LDM

The Stable Generalized Finite Element Method (SGFEM) is essentially an improved version of the Generalized Finite Element Method (GFEM). Besides of retaining the good flexibility for constructing local enriched approximations, the SGFEM has the advan
