An introduction to ABAQUS nonlinear finite element analysis and examples

First of all, we understand what numerical simulation is, numerical simulation is also called computer simulation, which uses electronic computers as a means to achieve the research of engineering problems and physical clarity and high-level problems and even various problems in nature through numerical calculations and image display methods, saving time and cost.

The three numerical analysis methods are the finite element method, the finite difference method, and the finite volume method. Finite element analysis is a modern calculation method that has developed rapidly for structural mechanics analysis. The most popular finite element analysis software at present are:

ansys、adina、abaqus、msc。One of the things we want to know about is that Abaqus focuses on structural analysis and currently does not have a fluid module.

The ABAQUS finite element analysis process is divided into three main phases:

1) Modeling phase.

2) Calculation phase.

3) Post-processing stage.

ABAQUS is one of the most advanced large-scale general finite element software in the world, which can analyze complex engineering mechanics problems, and its ability to control the huge solution scale and nonlinear mechanical analysis functions have reached the world's leading level.

Through the detailed analysis of abaqus finite element examples, this book introduces the analytical methods in the fields of abaqus static analysis, contact analysis, elastoplastic analysis, thermal stress analysis, multi-body analysis, frequency extraction analysis, instantaneous modal dynamic analysis, explicit dynamic analysis, as well as the skills of complex solid modeling, analysis calculation and post-processing.

Starting from practical application, this book focuses on the practical operation of abaqus and the solution of engineering problems, and teaches readers how to choose the corresponding functions of abaqus according to the characteristics of the problem, and seek the best solution to solve the problem. The book also focuses on the common mistakes and difficult problems encountered by users, as well as the common error messages and warnings of abaqus, and gives corresponding solutions.

"Abaqus Nonlinear Finite Element Analysis and Examples" is a book published by Science Press, and the author is Zhuang Zhuo.

Through the detailed analysis of abaqus finite element examples, this book introduces the analytical methods in the fields of abaqus static analysis, contact analysis, elastoplastic analysis, thermal stress analysis, multi-body analysis, frequency extraction and lingmin analysis, wangshan instantaneous mode dynamic analysis, explicit dynamic dynamic dynamic analysis, and explicit dynamic pure branch analysis, as well as the skills of complex solid modeling, analysis and calculation, and post-processing.

Finite Element Analysis and Applications Based on ABAQUS is an introductory guide and engineering analysis and scientific research tutorial based on ABAQUS software version published by Tsinghua University Press in 2009. The book is divided into two parts: the first and the second. The first part is mainly a basic introduction to the basic theory and software functions, and the second part selects a number of typical application cases of abaqus in the field of scientific research and engineering, involving the application research of various materials such as rubber, geotechnical and composite materials, and how to prepare for secondary development by writing user interface programs.

Zhuang Zhuang was born in June 1952. He graduated from Shenyang Jianzhu University in 1982 with a bachelor's degree in civil engineering, received a master's degree from Chongqing University in 1988, and received a doctorate degree from the National University of Ireland College in 1995. He is currently the Secretary of the Party Committee of the School of Aeronautics and Astronautics of Tsinghua University, a professor and doctoral supervisor, and the director of the National Finger Impulse Mechanics Experimental Teaching Demonstration Center.
