Khoroshun, E. Shikula] The structural theory of short-term damage is generalized to the case where undamaged components of an N-component laminate deform nonlinearly under loads that induce a combined stress state. The basis for this generalization is the stochastic elasticity equations for an N-component laminate with porous components whose skeleton deforms nonlinearly. The Huber-Mises failure criterion is used to describe the damage of microvolumes in the composite. The damaged microvolume balance equation is derived for the physically nonlinear materials of the composite components. Together with the macrostress-macrostrain relationship, they constitute a closed-form system of equations. This system describes the coupled processes of physically nonlinear deformation and microdamage. For a two-component laminate, algorithms for calculating the microdamage-macrostrain relationship and plotting stress-strain curves are proposed. Stress-strain curves are also plotted for the case where microdamages occur in the linearly hardening component and do not in the linear elastic component under simultaneous normal and tangential loads. The effect of the volume fraction of reinforcement and tangential load on the curves is examined Springer Science+Business Media, Inc., 2007 laminated composite nationallicence microdamage nationallicence physically nonlinear skeleton nationallicence combined stress state nationallicence simultaneous normal and tangential loads nationallicence Khoroshun L.
