Cracking a ceramic filter

Steven Butcher, Alex Crouse, and David Currin

 

 

A spring-loaded cylindrical rod was fired downward to break a ceramic filter, seen from the side. The filter is about the size of a household sponge and is used in filtering molten metal. This dynamic method of cracking the filter is one way of testing its strength.
