Brittle stress strain

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.
