Similarities between ductile material and brittle material  



Both are associated with the plastic deformation of the material under tensile loading. Ductility or brittleness is highly temperature dependent. For example, a brittle material can behave like a ductile one at an elevated temperature. Similarly, a ductile material at room temperature, when frozen, can automatically convert into brittle material. Ductility or brittleness of a material also depends on the inbuilt stress level. Under presence of high residual stress, a ductile material may fail without palpable plastic elongation.

Differences between ductile material and brittle material Solid materials that can undergo substantial prior to fracture are called ductile materials.

Solid materials that exhibit are called brittle materials.
