Elastic/Plastic Deformation. When a sufficient load is applied to a metal or other structural material, it will cause the material to change shape. This change in shape is called deformation. A temporary shape change that is self-reversing after the force is removed, so that the object returns to its original shape, is called elastic deformation.

stainless steel continuously decreases as the level of plastic pre-straining increases from 0% to 15%. A similar reduction in the fracture toughness of the pre-strained 316 material is also reported in [2]. Other studies of the influence of pre-straining on the fracture behaviour of a range of engineering materials can be found in e.g. [3-8].

We develop a mathematical model describing the processes of complex plastic deformation of structural materials (metals and their alloys) under multiaxial nonproportional paths of complex temperature and force loading. To obtain qualitative and quantitative assessment of the constitutive relations developed here, we study how the strain path shape affects the plastic behavior of metals.
