The energy release rate $${\displaystyle G}$$ is defined as the instantaneous loss of total potential energy $${\displaystyle \Pi }$$ per unit crack growth area $${\displaystyle s}$$, $${\displaystyle G\equiv -{\frac {\partial \Pi }{\partial s}},}$$ where the total potential energy is written in terms of the total … See more In fracture mechanics, the energy release rate, $${\displaystyle G}$$, 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 See more A handful of methods exist for calculating $${\displaystyle G}$$ with finite elements. Although a direct calculation of the J-integral is possible (using the strains and stresses outputted by See more • Nonlinear Fracture Mechanics Notes by Prof. John Hutchinson (from Harvard University) • Griffith's Strain Energy Release Rate on www.fracturemechanics.org See more There are a variety of methods available for calculating the energy release rate given material properties, specimen geometry, and loading conditions.
