How to predict the result by seeing the energy summary?

hello dear

Here is the energy summary for a bullet hitting a Aluminium plate.

i got the solution without any error but why KE did not decrease and internal increased?

Is the solution OK?

    The KE of the projectile is quite high. If the Aluminum plate is very thin, the projectile's KE may not drop much.

    Suggest you to reduce the Initial Velocity of the projectile and re-run the model to see if you can observe the drop of the projectile's KE and the increase of the plate's IE.

    Hello Dear cxquan

    You are correct aluminium sheet is having 2mm thickness and 750m/s.

    Is in energy Summary, KE is of bullet only not of the system?????

    Means to say Energy curve will show the Energy of the object which we are providing velocity?/

    Thank you
