Abstract:
Aking into account the microplasticity in the vicinity of the pores, an effective discharge equation is obtained. The influence of porosity on the residual deformation under uniaxial tension of a sample of a porous metal composite is taken into account. The nonlinearity in the deformations of the discharge curve, which is caused by microplasticity, is established. Numerical calculations of the residual strain as a function of the initial stress and porosity are given.
Keywords:
composite materials, matrix, microplastic zones, residual deformations, porosity.
