A worthy suggestion.
I bounced a one pound ball pein hammer, ball down,  off a steel anvil surface
from about 30 cm 30 times. Neither surface was deformed nor appreciably warm
to the touch.
I cropped an inch of steel off a 1/8 inch thickness angle. The temperature
was just sensibly higher.
 An obvious warming to the touch calls for a yielding object, I'd say.
