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.
