The plastic compressibility of 7075-T651 aluminum-alloy plate Academic Article

abstract

• The change in volume, and therefore the change in mass density, of an aluminum alloy was measured in uniaxial tension using clip-on extensometers. The experimental data do not agree with the assumption of plastic incompressibility found in the classical theories of plasticity. In fact, the elastic and plastic volume changes are of the same order of magnitude. Plastic anisotropy is thought to be the prime cause of this plastic compressibility. © 1986 Society for Experimental Mechanics, Inc.
