Micromechanics effects in creep metal-matrix composites

When placed under tensile loading, metals tend to creep, i.e., to elongate slowly over times of order hours to days. The creep rate is proportional to σ n where σ is the applied stress andn istypically in the range 2< n < 15. Ifnon-creeping, reinforcing particles are added to the metal, the creep rate of the composite is substantially reduced. On December 2, 1994 L. Craig Davis from Ford Motor Company described his recent work with J.E. Allison [1] in which the creep of metal-matrix composites was analyzed by finite element techniques. He posed, as an open problem, establishing by mathematical analysis the principal results of his calculations.
