The Force Cone Method: A New Thinking Tool
For Lightweight Structures

Abstract
The Force Cone Method developed by Claus Mattheck enables computer-free
topology designing and offers a profound knowledge for lightweight structures.
Thus the recently developed method enhances the series of so-called thinking
tools. The methods basic idea is the force distribution of a single force in an
elastic plane. Symmetrically placed cones appear in front of the force and behind
it. These cones intersect with 90-degree angles at primary points that quickly
lead to a structural design proposal. Furthermore the method is very useful for
the evaluation of structures and their lightweight potential. With the knowledge
of the load case it is easy to identify main tension and compression paths leading
to a deeper understanding of lightweight results. Also natural structures such as
trees can be understood in another way, highlighting structural principles at the
root, the leaf, the treetop or even the entire tree. Nowadays technical lightweight
solutions can be found with different methods, including the Soft Kill Option
(SKO) developed at the Karlsruhe Institute of Technology (KIT) 20 years ago.
The method resembles the biological mineralization process of living bone and
results in structures that can be seen as optimized lightweight design proposals.
The comparisons of those structures with the state of the art designs used in the
industry and with the ones found by the Force Cone Method indicate the high
potential of the new method. For the confirmation of the basic rules and
principles different assembly positions of force and supports as well as different
types of supports, such as fixed supports or torsion anchors, have been analyzed.
Keywords: force cone method, topology design, lightweight structure.
Keywords
