In fracture mechanics, the energy release rate,, is the rate at which energy is transformed as a material undergoes fracture. Mathematically, the energy release rate is expressed as the decrease in total potential energy per increase in fracture surface area, and is thus expressed in terms of energy per unit area. Various energy balances can be constructed relating the energy released during fracture to the energy of the resulting new surface, as well as other dissipative processes s

The rate of energy storage and release is a crucial metric for assessing the performance of a phase-change energy storage heat exchanger.
The energy release rate is defined as the instantaneous loss of total potential energy per unit crack growth area , where the total potential energy is written in terms of the total strain energy , surface traction , displacement , and body force by The first integral is over the surface of the material, and the second is over its volume .
However, the average thermal energy release rate only decreases by 1.6 %, 4.7 %, and 4.7 %, respectively. In the early stage of melting, a small amount of heat is stored directly by thermal conduction. During the melting process, the natural convection in PCM becomes the main heat transfer mechanism.
In fracture mechanics, the energy release rate, , is the rate at which energy is transformed as a material undergoes fracture. Mathematically, the energy release rate is expressed as the decrease in total potential energy per increase in fracture surface area, and is thus expressed in terms of energy per unit area.
Since the energy release rate is defined as the negative derivative of the total potential energy with respect to crack surface growth, the energy release rate may be written as the difference between the potential energy before and after the crack grows. After some careful derivation, this leads one to the crack closure integral
Compared to the L/D ratio, the specific surface area has a greater impact on the rate of energy storage and release. In this study, we have established an experimental platform featuring a shell and tube heat exchanger (STHE) combined with phase change material (PCM) to investigate its energy storage and release performance.
