- Tensors are a powerful tool for analysing mechanical states, see Tensors in Materials Science TLP.
- For an important example of the application of tensors in stress analysis, see Stress Analysis and Mohr's Circle TLP.
- There are other stress states, such as bending or torsion, see Bending and Torsion of Beams TLP.
- For a more detailed description and analysis of tensile test and hardness test, see Mechanical Testing of Metals TLP.
- To understand dislocations and work hardening further, see Mechanisms of Plasticity TLP.
- To explore slip in single crystals in more details, see Slip in Single Crystals TLP.
- Hardenability of a steel is a measure of the capacity of the steel to increase hardness and is measured by the Jominy end quench test. See The Jominy End Quench Test TLP.
- To explore creep further, see Creep Deformation of Metals TLP.
- In brittle fracture, the stress is larger at the crack tip. To describe this, we can introduce stress intensity factor K, from which we define the fracture toughness Kc in a specific geometry (the amount of stress required to propagate a preexisting flaw). See Brittle Fracture TLP.
- In ductile fracture, the resistance to fracture can be improved by absorbing more energy before fracture, this process is called toughening. See Toughening TLP.
