31. The faults then pushed through the Jurassic layers to the Cretaceous ductile stratigraphy. 32. Above this temperature the failure mode is ductile failure. 33. This is primarily accomplished through normal faulting and through the ductile stretching and thinning. 34. It is a hard, silvery grey, ductile , and malleable transition metal. 35. Whether polonium is ductile or brittle is unclear. 36. Salami is homogeneous in appearance and highly ductile . 37. That is why, generally speaking, metals are ductile and ceramics are brittle. 38. Pure metals are soft, tough and ductile with a high coefficient of friction. 39. It is ductile enough for deep drawing and weldable, but has low strength. 40. The flow stress is an important parameter in the fatigue failure of ductile materials.
