SHORT-TIME, BIAXIAL CREEP OF AN ALUMINUM ALLOY WITH ABRUPT CHANGES OF TEMPERATURE AND STATE OF STRESS.

Abstract

Short-time, biaxial creep experiments of an aluminum alloy are described which involved abrupt changes in temperature and state of stress. Results are discussed in terms of a creep surface concept similar to the yield surface concept of time-independent plasticity. Evidence that the creep surface changes size, shape, and location in response to creep strain is discussed. The contribution of metallurgical and viscoelastic effects to the complexity of the mechanical behavior are also discussed. (Author)
