The advent of digital imaging technology and huge increases in data-processing power have led to enormous advances in optical techniques for evaluating strain fields. A standardised test material designed for evaluating the capabilities of the most sophisticated optical systems using these techniques is described. The standardised test material presents a significant challenge to optical techniques for full-field strain evaluation by employing complicated and reproducible strain fields for which analytical solutions are available. The design philosophy and process employed in developing the standardised test material are described and sample results are presented. The relationship between a standardised test material and reference material for calibration is discussed.
