  We explore the distribution of the energy momentum tensor (EMT) around
quark--anti-quark and single quark at nonzero temperature in SU(3) Yang-Mills
gauge theory by extending our previous study on the EMT distribution in static
quark--anti-quark systems in vacuum. We discuss the disappearance of the flux
tube structure observed in the vacuum simulation. We investigate the total
stress acting on the mid-plane between a quark and an anti-quark and show that
it agrees with the force obtained from the derivative of the free energy. The
color Debye screening effect in the deconfined phase is also discussed in terms
of the EMT distribution.
