The mechanical properties of metallic materials refer to the behaviors exhibited by metallic materials under the action of external loads or the combined action of loads and environmental factors (temperature, medium and loading rate).
The common mechanical properties of metals are shown in the following table:
| Mechanical properties of metals | Common mechanical property indicators of metals |
| Strength | Yield strength, tensile strength, fracture strength |
| Plasticity | Elongation, reduction of area, strain strengthening index |
| Elasticity | Elastic modulus (stiffness), elastic limit, proportional limit |
| Hardness | Brinell hardness, Vickers hardness, Rockwell hardness |
| Resilience | Static toughness, impact toughness, fracture toughness |
| Fatigue | Fatigue strength, fatigue life, fatigue notch sensitivity |
| Stress corrosion | The intensity factor of the critical stress field for stress corrosion and the crack propagation rate of stress corrosion |
