Virtual Transition Marketplace NavyFST. Download Full PDF Package. .The phenomenon of increase in stress from D to E is known as strain hardening. The internal resistance force per unit area acting on a material or intensity of the forces distributed over a given section is called the stress at a point.. Stress is (a)External force (b)Internal resistive force (c)Axial force … Describing the stress, strain and deformation either in the reference or current configuration would make it easier to define constitutive models (for example, the Cauchy Stress tensor is variant to a pure rotation, while the deformation strain tensor is invariant; thus creating problems in defining a constitutive model that relates a varying tensor, in terms of an invariant one during pure rotation; as by definition … 0 b.
