Purpose: The purpose of this study is to introduce a new concept in engineered materials and that is truss substructured materials (TSMs). These materials would be engineered to express mechanical abilities that are seldom found in nature. Design/methodology/approach: This article starts with defining TSMs and how to classify and name TSMs. The article also introduces the theoretical modeling of TSMs, the software developed for analyzing TSMs and the parametric studies performed. Findings: After these studies, new materials are introduced that have abilities such as negative Poisson ratio in X and Y direction, negative Poisson ratio in one direction (either x or y), self-remodeling under stress. Research limitations/implications: The research is done in 2D, further studies in 3D using 3D printing are required to make the suggested materials a viable real-world solution. Originality/value: The main contribution of this research work is the proposed nomenclature that creates a system for researchers to experiment and create novel and unique versions of the proposed materials. Furthermore, some of the materials developed exhibit some unique properties that may create advances in engineering with further development.
