Abaqus FEA [4] [5] (antes ABAQUS ) es un paquete de software para el análisis de elementos finitos y la ingeniería asistida por computadora , originalmente lanzado en 1978. El nombre y el logotipo de este software se basan en la herramienta de cálculo del ábaco . [6] El paquete de productos Abaqus consta de cinco productos de software principales: [5]

  1. Abaqus / CAE , o " C ompleta A baqus E nvironment" (un backronym con una raíz en C omputer- A ided E ngineering [7] ). Es una aplicación de software que se utiliza tanto para el modelado y análisis de componentes mecánicos y ensamblajes (preprocesamiento) como para visualizar el resultado del análisis de elementos finitos. Un subconjunto de Abaqus / CAE que incluye solo el módulo de posprocesamiento se puede iniciar de forma independiente en el producto Abaqus / Viewer .
  2. Abaqus / Standard , un analizador de elementos finitos de uso general que emplea un esquema de integración implícito (tradicional).
  3. Abaqus / Explicit , un analizador de elementos finitos de propósito especial que emplea un esquema de integración explícito para resolver sistemas altamente no lineales con muchos contactos complejos bajo cargas transitorias.
  4. Abaqus / CFD , un C omputational F LUID D ynamics aplicación de software que proporciona capacidades avanzadas de dinámica de fluidos computacional con un amplio soporte para el preprocesamiento y de posprocesamiento proporcionado en Abaqus / CAE. [8]
  5. Abaqus / Electromagnetic , una aplicación de software de electromagnetismo computacional que resuelve problemas electromagnéticos computacionales avanzados.

Los productos Abaqus utilizan el lenguaje de programación de código abierto Python para la programación y la personalización. Abaqus / CAE utiliza fox-toolkit para el desarrollo de GUI .

Historia [ editar ]

El nombre de Abaqus se escribió inicialmente como ABAQUS cuando se lanzó por primera vez. La historia temprana de ABAQUS está estrechamente relacionada con la historia temprana de MARC Analysis Research Corporation . [9] El Dr. David Hibbitt y el Dr. Bengt Karlsson cofundaron la compañía más tarde conocida como Hibbitt, Karlsson & Sorensen, Inc., (HKS) en enero de 1978 para desarrollar y comercializar el software ABAQUS. [10] [11] [9]

Posteriormente, el Dr. Paul Sorensen se unió a la empresa. El logotipo original de la compañía ABAQUS es una calculadora ábaco estilizada, [6] y sus cuentas están configuradas para la fecha de lanzamiento oficial de la compañía el 1 de febrero de 1978 (2-1-1978). [12]

La versión 1 de ABAQUS se creó para un cliente específico: Westinghouse Hanford Company, que utilizó el software para analizar conjuntos de barras de combustible nuclear. La versión 3 de ABAQUS fue lanzada en junio de 1979. [13] En los primeros días, ABAQUS fue diseñado principalmente para el análisis no lineal estático y dinámico de estructuras, y el análisis no lineal constante y transitorio de transferencia de calor o problemas de conducción. [13] Inicialmente se distribuyó a través del servicio Cybernet de los CDC. La primera versión paralela de ABAQUS, la versión 5.4, se puso a disposición de los usuarios en 1995. [11]

The core product, eventually known as ABAQUS/Standard which is an implicit finite element solver, was complemented by other software packages including ABAQUS/Explicit, a dynamic explicit analysis package released in 1992, and ABAQUS/CAE, a finite element pre- and post-processing package released in 1999. The first official release of ABAQUS/Explicit was hand-delivered to M.I.T. in 1992.[12] Later on, the company's name was changed to ABAQUS, Inc. in late 2002 to reflect the company's focus on this product line. Then, in October 2005, the company with its 525 employees was acquired by Dassault Systèmes for $413 million or about four times the company's annual revenue of approximately $100 million.[9][14][15] After that, ABAQUS, Inc. became part of Dassault Systèmes Simulia Corp.

Dr. David Hibbitt was still with the company he co-founded as chairman while Mark Goldstein was president and CEO when the company was acquired by Dassault Systèmes. After 23 years of leadership, David Hibbitt retired in 2001; Bengt Karlsson and Paul Sorensen followed suit in the following year. All three are still living in New England.[12]

The headquarters of the company was located in Providence, Rhode Island until 2014. Since 2014, the headquarters of the company are located in Johnston, Rhode Island, United States.

Release history[edit]

The first version of ABAQUS was delivered/released in Sept. 1978.[10] Version 3 of ABAQUS was released in June 1979.[13] The first official release of ABAQUS/Explicit was in 1992.[12] Version 0 of ABAQUS/Viewer was released as a standalone product in 1998. The same features were made available as the Visualization module of ABAQUS/CAE when it was first released in 1999.[12]

In recent years, a new version of Abaqus has been released near the end of every year.

Applications[edit]

Abaqus is used in the automotive, aerospace, and industrial products industries. The product is popular with non-academic and research institutions in engineering due to the wide material modeling capability, and the program's ability to be customized, for example, users can define their own material models so that new materials could also be simulated in Abaqus. Abaqus also provides a good collection of multiphysics capabilities, such as coupled acoustic-structural, piezoelectric, and structural-pore capabilities, making it attractive for production-level simulations where multiple fields need to be coupled.

Abaqus was initially designed to address non-linear physical behavior; as a result, the package has an extensive range of material models such as elastomeric (rubberlike) and hyperelastic (soft tissue) material capabilities.

Here are some animated examples

Solution Sequence[edit]

Abaqus FEA software products used in Finite Element Analysis and their order of use.

Every complete finite-element analysis consists of 3 separate stages:

  • Pre-processing or modeling: This stage involves creating an input file which contains an engineer's design for a finite-element analyzer (also called "solver").
  • Processing or finite element analysis: This stage produces an output visual file.
  • Post-processing or generating report, image, animation, etc. from the output file: This stage is a visual rendering stage.

Abaqus/CAE is capable of pre-processing, post-processing, and monitoring the processing stage of the solver; however, the first stage can also be done by other compatible CAD software, or even a text editor. Abaqus/Standard, Abaqus/Explicit or Abaqus/CFD are capable of accomplishing the processing stage. Dassault Systemes also produces Abaqus for CATIA for adding advanced processing and post processing stages to a pre-processor like CATIA.

Solvers Comparison[edit]

The following is a comparison between the solver capabilities of Abaqus/Standard and Abaqus/Explicit.[16]

Notes

^* The more complex the contacts become, the more repetitive calculations ABAQUS/Standard has to solve, and the more time and disk space needed; ABAQUS Explicit is the optimal choice in this case

^** Like static elements (see the picture,) dynamic elements, thermal elements and electrical elements

^ ^*** Steady, Static and Constant loads are the same. Transient loads include: quasi-static loads (slowly varying loads in which the effect of inertial is small enough to neglect) and dynamic loads (faster varying loads).
