The modelling of nonlinear behavior of materials for Finite Element Analysis can be a vexing problem. A host of challenges exist, ranging from the difficulty of obtaining pertinent material data to the conversion of this data into the input files needed by the FEA program. Too often, the material models themselves are ill-suited to describe the observed material behavior. In this book, the authors frame the landscape of the problem and look for pragmatic ways in which the analyst can obtain good simulation results with existing, off-the-shelf material models available with the FEA programs.
The authors also seek to emphasize the fluid nature of this field. This book represents the current stable state of the art with respect to material calibration for FEA but does not seek to include matter that is being actively researched.
