摘要: Although there is mounting interest in the measurement of stresses composite materials after fabrication and/or use, few measurements to date have not taken into account three dimensional nature stress system such materials. Most data give only net stress, that is, difference between principal stresses. A procedure for a more complete (in reasonable time) developed here, including separation macrostresses and microstresses. If time does permit full investigation, lattice parameters component phases provide simple way sample hydrostatic due differential thermal contraction. The Barrett-Predecki method adding filler particularly promising those composites whose do appropriate diffraction peaks. This could also be used monitoring during useful life
