Customized abdomen insert response finite element model for crash test dummy and method

A method of creating a customized abdomen insert response finite element model for an abdomen insert of a crash test dummy, said method comprising the steps of:

• setting an abdomen insert stiffness at a maximum value and a minimum value;
• identifying two borderline sets of test data profiles for the abdomen insert that match with extremes of the test data profiles of the abdomen insert for the crash test dummy;
• varying material properties of components of the abdomen insert for the crash test dummy;
• defining a mapping function to adjust the material properties and contact algorithm parameters of components of the abdomen insert and allowing intermediate sets of the test data profiles to be interpolated from the test data profiles;
• and
• creating a single abdomen insert response finite element model for the abdomen insert of the crash test dummy with a user-defined input parameter for the abdomen insert response finite element model that defines a customized response, wherein the customized response is equal to an abdomen insert stiffness scale factor.
