Describe the materials after hammering
WebDuctility is the capacity of a material to deform permanently in response to stress. Most common steels, for example, are quite ductile and hence can accommodate local stress concentrations. Brittle materials, such as glass, cannot accommodate concentrations of stress because they lack ductility; they, therefore, fracture rather easily. When a material … WebAll solid materials can be bent. b. Solid materials can be bent depending on the property of the materials. c. When solid materials are bended, new material will be formed. d. …
