The D-term is, like mass and spin, one of the particle properties directly related to the matrix element of the energy-momentum tensor. But, unlike mass and spin, nearly nothing is known about this property experimentally. This fact as well as the physically appealing interpretation of the D-term form factor in terms of the mechanical forces inside hadrons has triggered a lot of interest in literature. Recent theoretical, phenomenological and experimental advances are presented.
