1. What is ABAQUS?
ABAQUS is a highly sophisticated, general purpose finite element program, designed primarily to
model the behavior of solids and structures under externally applied loading. ABAQUS includes
the following features:
Capabilities for both static and dynamic problems
The ability to model very large shape changes in solids, in both two and three
A very extensive element library, including a full set of continuum elements,
beam elements, shell and plate elements, among others.
A sophisticated capability to model contact between solids
An advanced material library, including the usual elastic and elastic – plastic
solids; models for foams, concrete, soils, piezoelectric materials, and many others.
Capabilities to model a number of phenomena of interest, including vibrations,
coupled fluid/structure interactions, acoustics, buckling problems, and so on.
The main strength of ABAQUS, however, is that it is based on a very sound theoretical framework
As an practicing engineer, you may be called upon to make crucial decisions based on the results
of computer simulations. While no computer program can ever be guaranteed free of bugs,
ABAQUS is among the more trustworthy codes. Furthermore, as you will see if you consult the

ABAQUS theory manual, HKS developers really understand continuum mechanics (since many of
them are Brown Ph.Ds, this goes without saying). For this reason, ABAQUS is used by a wide
range of industries, including aircraft manufacturers, automobile companies, oil companies and
microelectronics industries, as well as national laboratories and research universities.
ABAQUS is written and maintained by Hibbitt, Karlsson and Sorensen, Inc (HKS), which has
headquarers in Pawtucket, RI. The company
