A new edition (2001) in 3 volumes ((1) The Basics, (2) Solid Mechanics, (3) Fluid Dynamics) has been published by Butterworth-Heinemann Engineering, see this web page. *Description*:- FE analysis program for the solution of general problem classes.
*Platforms*:- The source code may be compiled for Windows, Linux or Unix operating systems.
*Availability*:- FEAPpv and PCFEAP may be downloaded from Dr. Taylor's website. The full FEAP may be obtained under license.
*Notes*:- FEAPpv is a small (stripped-down) version of FEAP; it
is described in the 5'th edition (2001) of the
*The Finite Element Method*. PCFEAP is the code from the 4'th edition (1987, 1991). The full FEAP program contains mesh utilities (1/2/3D), a wide range of solution algorithms, graphics options, an extensive element library, and constitutive models which include linear and finite elasticity, viscoelasticity with damage, and elastoplasticity.The program has a modular construction, with most of the package being independent of the particular problem being solved. The user needs to write a module which returns the appropriate

*element matrices*for the problem in hand. Then the macro language introduced by Taylor is used to set up the solution algorithm.See also Sanjay Govindjee's website which contains examples of user-defined macros, mesh commands, elements etc.

There is also the FeapUI project, which is creating a graphical interface for FEAP.
