Abstract
Stresses in the particles of two-phase composites are caused by particle/matrix differences in the coefficients of thermal expansion, elastic moduli and yield stress. The three types of stress are designated as σth, σel and σpl, respectively. When the matrix is strained plastically in uniaxial tension the thermal stress, σth, is relieved but this relief is counteracted by the development of σpl. It has proved experimentally difficult in the past to deconvolute the two effects. We show how this difficulty can be overcome by making measurements at a suitable elevated temperature and we also give an example of how the two effects interact at lower temperatures.
