The paper analyses the concept of GJ-integral. This concept is linked with the derivative of the energy functional with respect to a general perturbation of the domain and is useful in the study of many problems from sensitivity analysis. Applications of the GJ-integral method to numerous linear and nonlinear problems are indicated (Poisson equation, elliptic equation, linear elasticity, elastoplasticity, micro-polar elasticity).
