Allan F. Bower This electronic text summarizes the physical laws, mathematical methods, and computer algorithms that are used to predict the response of materials and structures to mechanical or thermal loading. Topics include: the mathematical descriptions of deformation and forces in solids; constitutive laws; analytical techniques and solutions to linear elastic and elastic-plastic boundary value problems; the use and theory of finite element analysis; fracture mechanics; and the theory of deformable rods, plates and shells. The text is intended for advanced undergraduate or graduate students, as well as practicing engineers and scientists.

To download these files, right-click the link and Save As The code can be run with the following input files.
The code is intended for educational purposes only - it contains bugs. The code includes: 1. Four simple example input files are provided. Linear, nonlinear and explicit dynamic solution procedures; 3. Routines to assemble and solve both symmetric and unsymmetric FEA equation systems, using the conjugate gradient method or LU decomposition. A bandwidth minimizer is also included.
Subroutines containing basic element level operations - integration points, shape functions and their derivatives for most standard 2D and 3D elements; 5.
An implementation of fully integrated 3D linear elastic elements, which can be used as a template for developing your own elements; 6. To run the code, you will need to: 1. Download the compressed folder 2. Uncompress the archive -e. Compile the code. The code will compile with free gfortran, however. The main program is stored in fecheap. The main program is stored in feacheap. If you are using gfortran, you should first download and install gfortran the mingw build seems to work fine on a Vista machine.
The input files can be edited with a standard text editor.
