Determination and Use of Material Properties for Finite Element Analysis: Book Review

by DatapointLabs9,870 views

This book is intended to be a companion to the NAFEMS book, "An Introduction to the Use of Material Models in FE". It informs Finite Element Analysis users of the manner and methodologies by which materials are tested in order to calibrate material models currently implemented in various FEA programs. While the authors seek first to satisfy the basic material models outlined in the companion book, they make important extensions to FEA used in currently active areas including explicit simulation.

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.
