The present thesis investigates the intricate relationship between geometrical changes and rubber-like materials tensile behaviour. Additive manufacturing technology has made fabrication a different game altogether, affording unbelievable freedoms not only in design but also choice of materials. The use of rubber like materials whose mechanical properties are unique in the field of flexible and resilient materials that provide a systematic way of “unravelling the geometric effect” on tense behaviour hold great potentiality. Using additive manufacturing techniques, many similar shape specimen samples but various geometric configurations was produced. These test samples subject to uniaxial tensile capture the material response to mechanical stresses. The post-processed measurements yielded accurate stress strain curves, elucidating the material behaviour in varying load settings. This study will compare stress, strain curves for samples with different geometry. It encompasses a wide array of geometric variables such as the aspect ratio, curvature, and density of infill. Through this study we are able to detect the complex and sometimes non-linear influence of geometrical parameters in a tensile load of an additively manufactured component. This is the reason why outcomes of such study contribute into deepening our basic knowledge about physical science and highlight the fact of how geometry influences tensile behaviour regarding potential additive manufacturing application. The study constitutes an enabler to enhancing the designs and manufacture process in additive manufacturing. Such an insight is of vital importance for use in areas such as soft-robotics prosthetics and flexible electronics as materials deployed within them need a very high degree of flexibility.
