Flexible Polyurethane (PU) foam samples with different densities and chemical formulations were tested in quasi-static stress-strain compression tests. The compression tests were performed using the Lloyd LR5K Plus instrument at fixed compression strain rate of 0.033 s-1 and samples were compressed up to 70% compression strains. All foam samples were tested in the foam rise direction and their compression test stress results were modeled using a constitutive Polymeric or Phenomenological Foam Model (PFM). In this research, a new constitutive PFM model that consists of mechanical systems such as dashpots and springs was formulated to be used for different strain rate experiments. The experimental compression test results for different strain rates were compared to the PFM model results for all foam samples. Both modeling and experimental results showed pretty good agreement. From curve fitting of the experimental tests with the PFM model; different mechanical materials' coefficients such as elastic and viscous parameters were computed. These mechanical parameters are indeed important characteristics for viscoelastic materials. This model can be used for constant and variable strain rates and for characterizing biomechanical material applications such as bone tissues, muscle tissues and other cellular materials. © 2014 IAU, Arak Branch.

Growth of the human population and global economic activity are placing significant strain on the life-carrying capacity of the Earth. Demands for food, clean water, shelter and energy are increasing as is the pollution generated through the consumption of these resources. The increase in demand for these resources is driven not only by population growth, but also from the desire to improve one's standard of living. In general, an improved standard of living requires an increase in the energy used per person. These two factors together lead to compounded growth in the demand for limited resources and in the production of hazardous pollutants. © Springer-Verlag London Limited 2011.

The case study presented in this chapter describes the design and implementation of a hybrid system for the elimination of engine idle in airport ground support vehicles. We will first examine the decision-making process by considering several combinations of renewable energy technologies. This will be followed by a discussion of why a PEM (Polymer Electrolyte Membrane) fuel cell/lithium-ion battery system is the most suitable design for this project. We will then discuss the details of the proposed design. The chapter will conclude in a discussion of the project results and a summary of the successes and limitations of the project along with proposed future work. © Springer-Verlag London Limited 2011.

There is growing interest in integrating fuel cells with batteries or supercapacitors to create stand-alone generators. These could be used in applications where diesel generators are commonly used today. The reason for wanting to do this is to reduce system cost. © Springer-Verlag London Limited 2011.

The case study presented in this chapter discusses the key decisions that factor into the design of a hybrid fuel cell/desalination (HFCD) system to supply a developing region with adequate electrical power and water. The focus of this case study is Caye Caulker, a Carribean island located off the coast of Belize. Caye Caulker has limited fresh water sources and currently uses diesel generators as its sole source of power. The goal of this case study is to replace these diesel generators with an HCFD system that can also provide Caye Caulker with potable water. © Springer-Verlag London Limited 2011.

This paper presents a unique approach for integrating a finite element analysis (FEA) model using a dynamic explicit of Abaqus with a nonlinear process of the mold's open/close phase in an injection molding machine. This opening/closing phase is considered to have one of the highest impacts on reducing an overall cycle duration since it has no impact on the final part quality. Reducing the overall cycle duration has a big positive impact on productivity and enhancing efficiency of the manufacturing processes of injection molding systems. Therefore, one of the objectives of the injection molding manufacturers is increasing efficiency by reducing the time duration of this phase to a possible minimum. In this work, a 3-dimensional (3D) solid model of the mold, toggle mechanism, and hydraulic cylinder were developed and then superimposed with Abaqus software to animate the motion of the movable part of the mold. The position of the movable part of the mold is traced and used as a controlled variable while the inputted force and initial velocity were considered as the manipulated variables. The innovation of this strategy is that the controller structure uses the nonlinear model to update the process variables at every sampling instant while the closed-loop control is executed. This allows the determination of the plant's variables resulting in a new set of the controller parameters with every sampling instant. Copyright © 2011 by ASME.
