Mechanical Engineering

Materials are subject to changes from temperature. We know thereare several states of matter: solid, liquid, gas, and plasma.However, within a solid-state, materials have their propertiesaffected, in particular brittleness. The Liberty ships of theSecond World War were often breaking from cold weather.

These failures highlighted a material fracture problem.

What causes these failures, what materials are affected, and arethere any that are not? How is brittleness calculated and measured(types of measurement) and what does this means for aircraftmaterial selection and design considerations? You may include theinfluence of this problem from a maintenance perspective.
