Homogenized properties of elastic–viscoplastic composites with periodic internal structures

摘要: Abstract A homogenization theory for elastic–viscoplastic composites with periodic internal structures is developed in rate and incremental forms by considering unit cells subjected to macroscopically uniform stress strain. The enables us incrementally compute the macroscopic as well microscopic strain states nonlinear time-dependent composites. effective problems which history of either macro-strain or macro-stress, a combination them, prescribed function time. As applications theory, transverse off-axial deformation metal matrix reinforced unidirectionally continuous fibers are analyzed discuss effects fiber arrangement orientation on behavior.
