Chemo-micromechanics of brittle solids
Journal of the Mechanics and Physics of Solids, 1992Abstract A s imple micromechanical model is formulated for a brittle solid reacting with water-borne aggressive chemical substances. Underlying physicochemical processes, diffusion, chemical reaction, expansion of reaction products and microcracking, are modeled on the microscale.

A micromechanical damageconstitutive model for solid propellant
2011 Second International Conference on Mechanic Automation and Control Engineering, 2011This paper studies the damage process induced by dewetting microcracks in composite solid propellant. A nonlinear viscoelastic constitutive model for composite soild propellant is presented. The damage variable D is derived from the microcrack system and is function of microcrack size density.

Micromechanism for Metallic-Glass Formation by Solid-State Reactions
Physical Review Letters, 1985Metallic-glass formation by solid-state reactions has been observed in multilayer Zr-Co diffusion couples and studied by cross-sectional transmission electron microscopy. Planar growth of a Corich amorphous phase proceeds from each interface of the unreacted sample, thus consuming the Co layers at a higher rate.

New micromechanism for strengthening in polycrystalline solids
Materials Science and Engineering: A, 1994Abstract A new micromechanism for strengthening in polycrystalline solids is suggested which is related to the role of quasiperiodic grain boundaries as the special strengthening elements during plastic deformation. This role is caused by the quasiperiodic structure of such boundaries and has no analogue for periodic grain boundaries.

Micromechanics of fracture of solid polymers in dynamic loading
Strength of Materials, 1990The results of investigation of the influence of temperature on the micromechanics of fracture ofpofymethyl methacrylate and epoxy materials in dynamic loading are presented, A method was developed for determination of the value characterizing the formation and development of microcracks in front of the front of the main crack.

A Micromechanical Model of Porous-Brittle Solids
1986There are many advantages to micromechanical models of material response. These are models that predict the behavior under load of materials by considering the behavior of microscopic structures embedded in an equivalent continuum1,2. We have derived a theoretical model framework that allows quasistatic plastic pore crush and brittle fracture along ...
