RISStatic and Dynamic Response of Beams on Nonlinear Viscoelastic Unilateral Foundations: A Multimode Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Nonlinear viscoelastic behavior is a characteristic of many engineering materials including flexible polyurethane foam, yet it is difficult to develop dynamic models of systems that include these materials and are able to ...
Identification of Nonlinear Viscoelastic Models of Flexible Polyurethane Foam From Uniaxial Compression Data
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flexible polyethylene foam is used in many engineering applications. It exhibits nonlinear and viscoelastic behavior which makes it difficult to model. To date, several models have been developed to characterize the complex ...
Development of a Multibody Model to Predict the Settling Point and Interfacial Pressure Distribution in a Seat–Occupant System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The location of the hipjoint (HPoint) of a seat occupant is an important design specification which directly affects the seat static comfort. Most car seats are made of polyurethane foam and so the location of the HPoint ...
