How to calculate the deformation of energy storage container

How do you calculate the energy stored by plastic deformation?

(1) A 1 = E s 1 + Q 1. If we isothermally anneal the accumulated defects and return the system to the initial state with the initial dislocation density ρ 0 along the path 1→3, the energy stored by plastic deformation in state 3 will be zero while the residual plastic strain will be ε 1.

What is stored energy in plastic deformation?

Technically, the stored energy predicted by these approaches and models is the macroscopic equivalent of energy associated with defects generated during plastic deformation. Using these models, important information regarding the stored energy in plastic deformation can be obtained (Ghosh et al., 2017).

How do you calculate the energy of elastic deformation?

Because elastic deformation is a completely linear process, the energy of elastic strain E e l can be estimated using (23) E e l = 1 2 V σ: γ e Fig. 4. Evolution of the total work of the external force with engineering strain under quasi-static compression for and orientations.

How is plastic deformation energy converted to heat & dissipated?

Apart from plastic deformation energy stored in the form of defects (such as dislocations, vacancies, etc.), the remaining is converted to heat and dissipated. The partition of plastic work converted to heat during plastic deformation has also been widely investigated.
