Flexural strength

The flexural strength is the measure of material's strength in a bent mode. The flexural strength becomes very practical when the geometry of the application is a structural/bulky volume and when the component service failure most likely occurs in bending mode. It is commonly expressed in the unit scale of MPa, which is equivalent to 10 6 Pa. 

Similar to the tensile strength measurement, it involves measurement of material's resistance at the breaking point. The measurement setup involves the application of force that bends the material from a point.The standard testing for flexural strength involves placing a material sample on its  two ends and then constantly applying force at a certain point until the material sample breaks apart. Throughout the bending force application, a characteristic stress-strain curve is obtained. The flexural strength is identified using this curve, particularly at the breaking point.
