An inverse modeling method for parameter identification of thermoplastics
from SPE Plastics Research Online
Polymers are widely favored in the transportation industry, whether as structural components or for the safety of passengers and pedestrians. Nevertheless, experience in the numerical modeling of polymers used in impact protection and structural systems is limited, generally because commercial finite-element software lacks robust material models. A new procedure simplifies the identification of true stress-true strain laws for the characterization of thermoplastics.
