Recent developments in polymer chemistries along with timely advancements in the field of additive manufacturing (AM) have expanded the possibilities for soft material application. Specifically, novel UV-curable, ultra-stretchable (hyperelastic) liquid resins have been generated for compatibility with continuous digital light processing (cDLP) AM, a subset of vat photopolymerization (VP). However, the use of these materials in relevant applications is impeded by a lack of thorough mechanical testing and subsequent material modeling to clarify behavior. This project aims to address this issue through (1) building a framework of multimodal experimental test data, (2) fashioning descriptive constitutive (material) models, and (3) scripting representative finite element simulations, all towards the implementation of hyperelastic materials in soft robotics.
