In order to estimate and improve the crashworthiness of practical automotive parts, dynamic crash test was conducted by using double hat specimen composed of the materials with different strength and thickness. Estimation method of the average force of the specimen was discussed. From the test results, it was clear that absorbed energy of the specimen composed of the materials with different strength and thickness of plate can be evaluated from the linear mixture law for the relations of the absorbed energy and the thickness of the materials used. And the “effective width theory” is useful way to estimate the average force of the parts.
