ABAQUS is a powerful finite element analysis software package for engineering simulations, covering problems from relatively simple linear analyses to many very complicated nonlinear analyses. ABAQUS has a rich element library which can simulate an arbitrary geometric shape. It has a materials library that can simulate the properties of typical engineering materials, including metals, rubbers, polymers, composite materials, concretes, compressible superelastic foams, and geological materials like soils and rocks. As a general simulation tool, ABAQUS not only solves a lot of structural (stress/displacement) problems, but also simulates many problems in other engineering fields, such as heat transfer, mass diffusion, thermal-electric coupling, acoustic analysis, rock and soil mechanical analysis (fluid percolating and stress coupling analysis), and piezoelectric media analysis.

The finite element model used in this paper to investigate the tension capacity of cover plate joints was developed with the aid of the ABAQUS 6.14 (2014). ABAQUS is a powerful tool that can incorporate material, geometric and boundary non-linearity cause by nonlinear elasticity, plasticity, large displacement, contact problem, etc. The numerical models were implemented using solid elements C3D8R defined by eight nodes with three degrees of freedom per node: translations in the nodal x, y and z directions.
Simulation and experimental study on effect of surface residual stresses in dry orthogonal micro turning sample
Published in Australian Journal of Mechanical Engineering, 2023
ABAQUS/Complete ABAQUS Environment is a mechanical software utilised to design and simulate any mechanical part, assemblies and envisions their FEM result. ABAQUS/CAE likewise gives a particular module to perform welding simulations called ABAQUS Welding Interface (AWI). AWI is the interface which first leads a transient thermal analysis and makes another model for structural simulation of the welding part. It uses the yield of transient thermal analysis and accepts the temperature variations as a contribution to structural simulation. It requires different sources of inputs, such as material properties, the melting point of the metal, Boltzmann’s constant, meshing details, etc. Every FEM model comprises of three phases. Modelling and Pre-processing is the initial phase where an input model is made which consists of material properties, part model, meshing, load and boundary conditions of the model.. In third stage, post-processing, results are seen as animations of differing loads or temperatures whichever appropriate. The prerequisites of AWI to perform welding analysis are material properties at variable temperatures, weld plate and weld measurements, weld temperature, ambient temperature, Boltzmann constant and interaction properties between the materials.
Meta-model based multi-objective optimisation method for computer-aided tolerance design of compliant assemblies
Published in International Journal of Computer Integrated Manufacturing, 2019
In this study, ABAQUS software is used as a commercial software for the finite element analysis. Figure 5 shows the assembly modelled in ABAQUS® software and the corresponding fixtures and the control points. After joining two panels to each other, the fixture 1–5 and the fixture 2–2 are released. In order to create an initial gap in the assembly, the geometrical deviations as initial tolerances of the connection points on the panel 1 are imposed, while panel 2 has not any initial deviations. Six points CP1, CP2, CP3 on the panel 1 and CP4, CP5, CP6 on the panel 2 are KPCs which are inspected after the assembling process (see Figure 7).

In this example, the Abaqus® Scripting Iterative is adopted to handle complex structures. Abaqus is a general purpose commercial software package widely used in the aerospace, civil, mechanical and automotive industries. In each iteration, the FE calculation process is done by Abaqus/CAE; Matlab® reads data exported form Abaqus/CAE and solves the optimization problem.
