This book is intended as an essential study aid for the finite element
method. Based on the free computer algebra system Maxima, the authors
offer routines for symbolically or numerically solving problems in the
context of plane truss and frame structures, allowing readers to check
classical 'hand calculations' on the one hand and to understand the
computer implementation of the method on the other. The mechanical
theories focus on the classical one-dimensional structural elements,
i.e. bars, Euler-Bernoulli and Timoshenko beams, and their combination
to generalized beam elements. Focusing on one-dimensional elements
reduces the complexity of the mathematical framework, and the resulting
matrix equations can be displayed with all components and not merely in
the form of a symbolic representation. In addition, the use of a
computer algebra system and the incorporated functions, e.g. for
equation solving, allows readers to focus more on the methodology of the
finite element method and not on standard procedures.
