报告摘要：The crash of the Germanwings Flight 9525 is the most high-profile airlines accident in the year 2015. The airplane "pulverized", i.e.,broke up into pieces, in the mountains of the French Alps after thesuicidal control by co-pilot Andreas Lubitz. In this talk, we use impactmechanics and engineering to model and simulate this air crash. The physical model is mostly based on the PDEs in the Johnson-Cook model. Numerical computations are based on the finite element methods and the use of LS-DYNA and ANSYS Explicit Dynamics software. One can see how and under what conditions an airplane could pulverize through video animations obtained from supercomputer results.
