In earthquake engineering, a structure’s earthquake resistance is quantified by a combination of “demand” for this property and behavior class. This property characterizes the conditions in which mylonites shear and undergo metamorphism. This material property exists below a transition zone in the lithosphere that typically corresponds to the region of maximum seismicity. In regions of the crust with this property, compression of rock may cause it to fold into synclines and anticlines. Fault zones extend downwards into a shear zone with this property, which exists at depths where temperature and pressure is high enough that rocks no longer undergo brittle fracture. For 10 points, name this property of materials that can undergo significant plastic deformation before fracture, like copper. ■END■
ANSWER: ductility [or ductile; accept ductility demand; accept ductile zones or ductile shear zones; accept plasticity or plastic deformation until “plastic” is read; prompt on deformation until read by asking “what type of deformation?”; prompt on brittle–ductile transition zone by asking “which of those properties?”; prompt on shear or shear stress by asking “shear occurring in materials with what property?”]
