micro mechanic modeling of RVE in abaqus

Hello All,

I am new to the field of Micromechanincs and continum mechanics and my first assignment is FEM modeling of a unit cell or RVE using abaqus. My RVE is rectangular matrix with single fiber in the centre. No symmetry is being used. I have read research papers and the general principal seen was using normal and shear loads individually on unit cell to obtain colums of stiffness matrix. But, as always, none of the research paper talked of ground rules or step by step approach towards finding a constitutive law from a micromechanics analysis.
This may seem trivial, but for a started like me, is a conundrem and can save me lot of time that i can use to explore continum mechanics.
年代o can we establish a step by step approach for newbess.

looking forward to replies...
