Multi-material Fused Deposition Modelling (FDM) enables the cost-effective realization of designs in complex geometries built with multiple materials. However, achieving an adequate level of bonding strength between different materials remains a significant challenge. Besides the traditional way of addressing this challenge by strengthening material bonding at the molecular scale by optimizing the printing parameters, introducing a new design methodology that creates stronger multi-material interface geometry could also offer effective solutions. This work studied the mechanical properties of multi-material printed objects, with a particular focus on the interface zone formed between different materials at their geometrical boundaries. A new mathematical simulation …

Biomechanical Evaluation Of Hand Representation For Typing In Virtual Reality, Mobasshira Zaman
Graduate Research Theses & Dissertations
Virtual reality (VR) is becoming popular in the workplace recently. Text entry is thus now important for efficient office use and occupational use of VR, and VR paired with a conventional keyboard is suitable for long text entry. There has been a lack of research on physical demand, posture, motion, and cognitive demand, along with the performance of typing on VR. Presence of virtual hands while typing in VR may affect typing performance, physical demand, and posture. The focus of this study was to evaluate the biomechanical effect of hand representation for typing on VR using a conventional keyboard. Fifteen …
