Numerical Simulation of Pride Vehicle Components Crash to Barrier, using Johnson-Cook Ductile Damage Criterion

Today, the great vehicle companies use of computational simulation of vehicle crash and different software to avoid spending too much time and cost. In this investigation first, applying the Johnson-Cook ductile damage criterion in the ABAQUS explicit code, crash of a few important components of Pride vehicle such as fender, hood, door, and rear trunk which are most at risk of crash to barrier are simulated. Speed boundary conditions, barrier shape, and impact angle are adopted from the real accidents and implemented into the software. Carrying out the simulations, the results of deformation and damage in any of the above mentioned parts are predicted, maximum damage zones and near to failure are identified. Then, simulation results are compared with the results of the actual samples, to evaluate the Johnson-Cook damage criterion and material properties. Comparison of the numerical and real results reveal that the Johnson-Cook damage criterion can well predict the deformations and strength of different parts of the car through the crashing to barrier.
