Abaqus Analysis User’s Manual Volume I Version 6.7 - Introduction, Spatial Modeling, and Execution

This manual is a reference guide to using Abaqus/Standard (including Abaqus/Aqua, Abaqus/Design,and Abaqus/Foundation) and Abaqus/Explicit. Abaqus/Standard solves a system of equations implicitlyat each solution “increment.” In contrast, Abaqus/Explicit marches a solution forward through time insmall time increments without solving a coupled system of equations at each increment (or even forminga global stiffness matrix). Throughout the manual the term Abaqus is used to refer collectively to bothAbaqus/Standard and Abaqus/Explicit; the individual product names are used when information appliesto only one product. Product identi
firs appear at the beginning of each section in the manual (excludingoverview sections) indicating the products to which the information in the section applies.The manual is divided into several parts:
• Part I, “Introduction, Spatial Modeling, and Execution,” discusses basic modeling concepts inAbaqus, such as defining nodes, elements, and surfaces; the conventions and input formats thatshould be followed when using Abaqus; and the execution procedures for Abaqus/Standard,Abaqus/Explicit, Abaqus/CAE, and several utilities that are provided with the Abaqus system.
• Part II, “Output,” describes how to obtain output from Abaqus and the format of the results (.fil)file. It also describes the output variable identifiers that are available.
• Part III, “Analysis Procedures, Solution, and Control,” describes the analysis types (static stressanalysis, dynamics, eigenvalue extraction, etc.) that are available. Detailed discussions of thedifferences between how Abaqus/Standard and Abaqus/Explicit solve finite element analyses areprovided in this chapter.
• Part IV, “Analysis Techniques,” discusses various analysis techniques available in Abaqus such assubmodeling, removing elementsorsurfaces, and importing results from a previous simulation todefine the initial conditions for the current model.
•
Part V, “Materials,” describes the material modeling options and how to calibrate some of the moreadvanced material models.
• Part VI, “Elements,” describes the elements available in Abaqus.
•
Part VII, “Prescribed Conditions,” describes the use of prescribed conditions, such as distributed loads and nodal velocities.
•
Part VIII, “Constraints,” discusses the use of constraints, such as multi-point constraints.
•
Part IX, “Interactions,” discusses the contact and interaction models available in Abaqus.
