The crashworthiness of auto–body structures is one of the important issues in the automotive industry. The crash analysis with finite element methods has been conducted in order to evaluate the crashworthiness of auto–body structures. In the car crash, auto–body structures undergo deformation with a wide range of strain rate from 0.001/sec to 500/sec. Since the material properties of steel sheets depend on the rate of deformation, in order to ensure the impact characteristics of auto–body structures accurately, the dynamic behavior of sheet metals must be examined and applied to the finite element model appropriately. This research is concerned with standard uncertainty evaluation of tensile properties of steel sheets for auto–body structures at intermediate strain rate from 0.1/sec to 100/sec. An analytic model is established to evaluate standard uncertainty of the measurand and sensitivity coefficients of each input quantities. The measurand is true stress with respect to true strain measured by tensile test at the intermediate strain rate and the input quantities are load and displacement data during the tensile test and initial dimensions of specimen. In the uncertainty evaluation, uncertainty budget is reported and all of the uncertainty components in measuring and signal processing procedure are considered.
