A simplified description of viscoelastic behavior of polymers as illustrated with biaxially-oriented poly(ethylene terephthalate)
1978
A rheological model of solid polymers is proposed. Its mechanical analog is a parallel of a linear spring and a Maxwell element with variable viscosity. The viscosity of the dashpot is allowed to change with stress both directly, by an Eyring-type mechanism, and through free volume changes according to the Doolittle equation. Predictions of the model reproduce many of the features shown, especially after yielding, by constant velocity stress-strain, stress-relaxation and creep data taken at room temperature on biaxially-oriented poly(ethylene terephthalate) over a wide range of loading rates.
Dual Perspectives on the Role of Artificially Intelligent Robotic Virtual Agents in the Tourism, Travel and Hospitality Industries
2018
Robotics and artificial intelligence are challenging extant business services and fundamentally impacting business relationships and processes. While studies have elaborately investigated social robotic interactions in medical and health-related domains, studies are limited on artificially intelligent robotic virtual agents (AIRVA) and their impacts on consumer behavior in tourism and hospitality services. Building on the theories of user experience (UX), user interface (UI) and customer experience, this study conceptually examines the dual-value effects of AIRVA to the customer and the firm. It analyzes the customer journey and highlights critical touchpoints AIRVA deepens the customer exp…
