The structural description of the metamorphic mechanism is an important part of its structure, which is the basis of analysis and synthesis. Therefore, we introduce a comprehensive whole information matrix. The novel method to describe the topological structure of metamorphic mechanism in all the configurations was proposed in the paper. We have put painstaking effort into building the matrix.

Elastic systems that undergo large deformations are difficult to analyse because, while deforming, their mechanical properties change nonlinearly, which makes it difficult for designers to use them. In this work we make use of a graphical representation of the mechanical behaviour of a selected elastic object, a spiral spring, to facilitate the understanding of its behaviour. The use of these graphs is illustrated by generating peculiar examples of systems with many stable configurations.
