The tensile stress-strain response of polymers for large deformations can be obtained in many ways. Two methods are presented and compared to a true constant strain rate controlled tension test. The differences in the results suggest that improved modeling of polymers with respect to strain rate can be achieved using the true constant strain rate test(More)
– This paper describes a new curriculum, Product Design and Innovation (PDI), which aims to balance the traditional approaches of Industrial Design and Engineering Design with the approach of Science and Technology Studies(STS). Students will develop a general engineering knowledge through meeting the degree requirements for Engineering Science, and a set(More)
Integral attachment features are a growing method of joining plastic parts. Guidelines and equations that can predict the performance of features are needed for more efficient design. A design of experiments approach has been used to generate approximate second-order equations (response surfaces) which can calculate the insertion and retention forces for(More)
Traditional integral snap-fit attachment design focuses almost exclusively on the individual locking features, such as cantilever hooks, bayonet-fingers, compressive hooks and others'. The positioning and orientation of other significant features on parts, such as those that facilitate or enhance engagement and eliminate unwanted degrees of freedom left by(More)
Parameter sensitivity is defined as the estimation of changes in the modeling functions and design variables due to small changes in the fixed parameters of the formulation. There are currently several methods for estimating parameter sensitivities which either require difficult to obtain second order information, or do not return reliable estimates for the(More)
Integral attachment features are a growing method of joining plastic parts. Guidelines and equations that can predict the performance of features are needed for more efficient design. A design of experiments approach with 2-D and 3-D finite element methods was used to generate approximate linear response surfaces based on feature geometry which can(More)
