WebThe stress-strain curve measures toughness under a gradually increasing load. The material must be both strong and ductile to be tough. The following figure shows a typical stress-strain curve of ductile and brittle materials. For example, brittle materials (like ceramics) that are strong but with limited ductility are not tough; conversely ... It is possible to distinguish some common characteristics among the stress–strain curves of various groups of materials and, on this basis, to divide materials into two broad categories; namely, the ductile materials and the brittle materials. Ductile materials Ductile materials, including structural steel and many … See more In engineering and materials science, a stress–strain curve for a material gives the relationship between stress and strain. It is obtained by gradually applying load to a test coupon and measuring the deformation, … See more A schematic diagram for the stress–strain curve of low carbon steel at room temperature is shown in figure 1. There are several stages showing different behaviors, which suggests different mechanical properties. To clarify, materials can miss … See more Generally speaking, curves representing the relationship between stress and strain in any form of deformation can be regarded as stress–strain curves. The stress and strain can be normal, shear, or mixture, and can also can be uniaxial, biaxial, or … See more • Elastomers • Plane strain compression test • Strength of materials See more

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. ...
