The elastic energy-momentum tensor
Journal of Elasticity, 1975The application to continuum mechanics of the general methods of the classical theory of fields is advocated and illustrated by the example of the static elastic field. The non-linear theory of elasticity is set up in the most convenient form (lagrangian coordinates and stress tensor).

On the Material Energy-Momentum Tensor in Electrostatics and Magnetostatics
2006The notion of material force arises in a natural way in materials with ‘defects’ or in inhomogeneous materials. This notion, which is intimately related with that of material energy-momentum tensor, has been widely and successfully employed in crack-propagation problems, in phase-transition problems and others. In elasticity, there is general agreement

On redefinitions of the energy momentum tensor
Annals of Physics, 1975Abstract We analyse some redefinitions of the energy-momentum tensor of Classical Electrodynamics. Usually it has been considered as a necessary and sufficient criterion for redefining the energy-momentum tensor that the new tensor yields the “true” equation of motion of the electron, that is, the Lorentz-Dirac equation.

Energy–momentum tensor in the microscopic plasma model
Canadian Journal of Physics, 1976An energy–momentum tensor for the microscopic plasma model is constructed from the action integral by allowing for dynamics of special relativity. The energy density is then identified with the 44-component of the energy–momentum tensor. The result is compared with that obtained from an ad hoc method with the Legendre transformation.

In Sect. 1.2.7, Chap. 1, it is found that the electron spin torque is counterbalanced by the chiral electron density. In Sect. 1.2.8, Chap. 1, it is found that the spin vorticity of electron contributes to the kinetic momentum of electron, which raises a simple but “odd” question: what is momentum of electron spin?
