Abaqus is a set of powerful finite element software for engineering simulation, and its solution ranges from relatively simple linear analysis to many complex nonlinear problems. Abaqus includes a rich cell library, which can simulate any geometric shape. And has a variety of types of material model library, which can simulate the performance of typical engineering materials, including metal, rubber, polymer materials, composite materials, reinforced concrete, compressible superelastic foam materials and geotechnical materials. As a general simulation tool, Abaqus can not only solve a large number of structural (stress/displacement) problems, but also simulate many problems in other engineering fields, such as heat conduction, mass diffusion, thermoelectric coupling analysis, acoustic analysis, geotechnical engineering analysis (fluid seepage/stress coupling analysis), piezoelectric medium analysis and so on.
Abaqus provides users with a wide range of functions and is very simple to use. A large number of complex problems can be easily simulated by different combinations of option blocks. For example, a complex multi-component problem can be simulated by combining the option blocks that define the geometric dimensions of each component with the corresponding material property option blocks. In most simulations, even for highly nonlinear problems, users only need to provide some engineering data, such as the geometric shape, material characteristics, boundary conditions and load conditions of the structure. In nonlinear analysis, Abaqus can automatically select the corresponding load increment and convergence limit. He can not only choose the appropriate parameters, but also constantly adjust the parameters to ensure that the accurate solution can be obtained effectively in the analysis process. By precisely defining the parameters, users can control the numerical calculation results well.
Abaqus has two main solving modules-ABAQUS/Standard and Abaqus/Explicit. Abaqus also includes a graphical user interface that fully supports the solver, that is, the pre-and post-processing module of human-computer interaction-ABAQUS/CAE. Abaqus also provides special modules to solve some special problems.
Abaqus is widely regarded as the most powerful finite element software, which can analyze complex solid mechanics structural mechanics systems, especially control very large and complex problems and simulate highly nonlinear problems. Abaqus can not only do mechanical and multi-physical field analysis of a single part, but also do system-level analysis and research. Compared with other analysis software, the characteristics of Abaqus system-level analysis are unique. Abaqus has been widely used in industry and research in various countries because of its excellent analytical ability and reliability in simulating complex systems. Abaqus products have played a great role in the research of a large number of high-tech products.
