Hardness is dependent on ductility, elastic stiffness, plasticity, strain, strength, toughness, viscoelasticity, and viscosity. ABS combines the strength and for its hardness, gloss, toughness, and electrical insulation properties. The characteristics of wooden joints - strength, flexibility, toughness, appearance, etc. The binder imparts properties such as gloss, durability, flexibility, and toughness. The honey badger is notorious for its strength, ferocity and toughness. These castings tend to have poor ductility, toughness, and fatigue resistance. West was also regarded for his extreme mental toughness and his exemplary work ethic. Vanadium improves the wear resistance, toughness, and ease of sharpening. Moderate amounts of stress were associated with improvements in the traits of mastery and toughness. Fisher was perhaps best known for his leadership, toughness, and clutch playmaking ability. These polymers are known for their toughness and stability at high temperatures. These covalent bonds between peptide chains confer extra toughness and rigidity. There are special grades that offer higher mechanical toughness, stiffness or low-friction/wear properties. A variety of modifications can be made to improve impact resistance, toughness, and heat resistance. Also, low elasticity translates to low toughness.
