One-Dimensional Finite Elements (PDF)

In this introduction, the finite element method is broken down in its complexity to one-dimensional elements. Thus, the mathematical description remains largely simple and manageable.

The emphasis in each chapter is on explaining the method and understanding it. Readers learn to understand the assumptions and derivations in various physical problems in structural mechanics and to critically evaluate the possibilities and limitations of the finite element method.

This approach enables the methodical understanding of important topics, such as plasticity or composites, and ensures an easy entry into more advanced application areas. Detailed calculated and commented examples and further tasks with short solutions in the appendix support the learning success.

In the third edition of this textbook, the basic concept for the treatment of the finite element method with one-dimensional problems has been retained. Additionally, thermoelasticity has been included, as well asnumerous tasks with solutions supplemented.
