説明

For 400MPa grade steel and 490MPa grade steel, the authors suggested the model that considered the maximum load and behavior after the maximum load of stress strain relationship of the steel material. A material test specimen was analyzed using the input of this material model and compared elasto-plastic behavior after the maximum load and the propriety of the modeling was confirmed. Finally, the authors examined statistics value of mechanical property of steel materials and gave a standard stress strain relationship of steel materials by this model.
