Brittle stress strain

WebBrittle fracture occurs suddenly and catastrophically without any warning. This is a consequence of the spontaneous and rapid crack propagation. However, for ductile fracture, the presence of plastic deformation gives … WebJun 3, 2024 · Stress and strain curves for brittle, hard (but not ductile) and plastic materials are different. The curve for these materials is simpler and can be learned very easily. We shall focus on the stress-strain curve of ductile materials. But before we delve deeper into that, let’s take a look at another important concept – Hooke’s law. ...
