An exact expression of energy release rate for geometrical nonlinear elastic fracture mechanics is obtained for an infinite plate with central crack under uniform stress normal to crack surfaces.
The fracture of the electronic components is predicted through Comparing the experimental data of strain energy release rate.

The results show that using the encapsulated delayed release breaker may improve the proppant pack fracture conductivity and increase the cumulative oil and gas production capacity.
