Basic Sciences - Brittle VS Ductile

Description

In a lesson on Basic Sciences, the topic of brittle versus ductile materials, specifically ceramics and metals, is discussed. The lecture begins by presenting a stress-strain graph, where strain is plotted on the X-axis and stress on the Y-axis, indicating the zones of elastic and plastic deformation that materials undergo.



Brittle materials, such as ceramics, are defined as having a linear stress-strain relationship that results in failure without significant plastic deformation; they exhibit a longer elastic zone leading into a short plastic region before breaking. Conversely, ductile materials, typically metals, can endure substantial plastic deformation prior to failure, allowing them to absorb more stress before breaking.



The lesson clearly differentiates between these two categories of materials, emphasizing the properties that define their behaviors under stress.
