Abstract: A dynamic model of injection molding developed from physical considerations is used to select PID gains for pressure control during the packing phase of thermo-plastic injection molding. The ...

Abstract: An experimental and analytical investigation was undertaken to improve understanding of the form of long fiber reinforced thermoplastic sheets. The materials tested contained 30 percent by weight ...

Abstract: Thermoplastic composite materials hold considerable promise for increased use in low cost high volume applications because of the potential for processing by solid phase forming. Unfortunately, ...

Abstract: The strain-based approach to fatigue life prediction usually relies on the conventional strain-life equation which correlates the elastic and plastic strain to the life. The correlation is based ...

Abstract: A set of data fitting algorithms are presented for determining the cyclic material properties used in the local strain approach to fatigue life prediction. These properties are obtained by ...
