ptemberAbstract: On the ba of the characteristic analysis in the process with the car crash into guardrail in our country, considering that full-scale test requires a large amount of manpower and resources and impossible to repeat, numerical method is ud in this paper.Through the finite element software ABAQUS to establish solid model of the car, and reinforced concrete guardrail elastic-plastic model, the whole crash process of different angles and velocities impact load. Focus on the analysis of the stress function and damage area and energy change when the reinforced concrete guardrail was hit in highway.
