The daily puzzle:
What does '*****' mean in the following text?
"A material is ***** if, when subjected to stress, it breaks without significant deformation (strain). ***** materials absorb relatively little energy prior to fracture, even those of high strength. Breaking is often accompanied by a snapping sound. ***** materials include most ceramics and glasses (which do not deform plastically) and some polymers, such as PMMA and polystyrene. Many steels become ***** at low temperatures (see ductile-***** transition temperature), depending on their composition and processing."--++--++--
