Brittle materials such as glass do not possess a single characteristic strength. The strength of the material is dependent on the distribution of cracks or surface flaws. These factors, coupled with the inherent brittleness (cause of catastrophic or rapid failure) mean that extremely conservative design approaches are typically used for optical elements(More)
Modeling the effects of stress birefringence is critical for polarization sensitive optical systems. Optical design and optomechanical software tools to model stress birefringence are discussed and illustrated for three examples. The first example compares retardance in calcium fluoride lenses as a function of shape. The second example discusses the(More)
Proper finite element modeling of nearly incompressible bonds which are commonly used to mount optics requires special considerations. Modeling difficulties arise due to the geometries of the mounting designs and the incompressible nature of the bonding materials involved in many applications. Therefore, specific methods of modeling must be employed. Such(More)
Applied and partnered research at Emily Carr University takes place within four active research centres: <b>Social and Interactive Media Centre (SIM):</b> Focused on interaction and communication design, and entrepreneurship. <b>Health Design Lab (HDL):</b> Applies solution-focused, human-centred research methodologies to complex problems in health care.(More)
In this paper we discuss the low-volume production of an interaction design research product known as the tilting bowl. The form of the tilting bowl was designed with 3D modeling tools and utilized digital fabrication for rapid prototyping. The final form was produced in a small number of glazed ceramic forms with embedded electronics and actuators. We(More)
