... relations that describe the response of the system in terms of one quantity, when its conjugate is varied. The relation is usually taken to be linear (approximation) and the coefficient is a material constant. An example are the elastic moduli in Hooke’s law. sij = Cijkl ekl (Cijkl are called stiffn ...
