Method of material modeling for crash test dummy finite element models |
摘要 |
A computer method of material modeling for crash test dummy finite element models includes the steps of making a material card for the material, applying the material card to validate a finite element model of a crash test dummy component, determining whether the finite element model is acceptable, ending the method if the finite element model is acceptable, and adjusting a relative volume (J) range for the material to make the material soft or stiff if the finite element model is not acceptable. |

1. A computer method of material modeling for crash test dummy finite element models, said method comprising the steps of:
providing a computer; making an initial range for a relative volume (J) for a material of a crash test dummy component using the computer; checking lower and upper bounds of the initial range for the relative volume (J) against predetermined values using the computer; calculating a strain work of the material based on the relative volume (J) using the computer; evaluating the strain work based on the relative volume (J) using the computer; calculating a work error of the strain work based on the relative volume (J) using the computer; determining whether the work error is less than a first predetermined tolerance using the computer; outputting the relative volume (J) if the work error is less than the first predetermined tolerance using the computer; making a material card for the material of the crash test dummy component with the outputted relative volume (J) using the computer; providing a finite element model for the crash test dummy component using the computer; applying the material card in the finite element model to validate the finite element model using the computer; determining whether the finite element model is acceptable; ending the method if the finite element model is acceptable; and adjusting a value for the relative volume (J) for the material card to make the material soft or stiff if the finite element model is not acceptable. |
