Strength should not be confused with toughness. Toughness is a measure of the ability of a material to absorb energy prior to failure. A strong brittle material will probably be less tough than a weaker but more ductile material. Under impact load-... 

Part toughness. Toughness is measured by calculating the area under the load-deflection curve, from initial load to part failure. The toughness of the part is applicable for both load- and deflection-controlled applications. 

The properties required for thermal stress analysis Included Young s modulus, Poisson s ratio, thermal conductivity, thermal expansion coefficient and specific heat. The CARES analysis requires strength data (from which the Weibull parameters are calculated) and Poisson s ratio. Fracture toughness was also measured. Although this parameter is not required for the fast fracture prediction made by CARES, it 1s used in life-time prediction and is related to the properties used in the reliability analysis. Strength measurements, which are the basis of reliability predictions, are controlled by both the size of flaws inherent in ceramic materials and the fracture toughness. Toughness represents the ability of a material to tolerate flaws.
