A Study on the Impact Characteristics of the Composite Materials for Low Velocity to Be Applied a Rail Vehicle

철도차량에 적용될 복합재료의 저속충격특성에 관한 연구

In this study, the property against low velocity of the compesite material, which will be applied a rail vehicle, is shown using experiment and a finite element code. The property can be denoted the resistance of impact force, which is defined by maximum impact force over damage area. A damage propagation model is necessary to estimate accurately the impact property of a composite material through FEM code.
