【Abstract】 As a heterogenous material,composites have a significant structural mechanism.The mechanical behaviour and failure mechanism of composites depend significantly on its microstructure and the properties of each constituent.It is very important to study the relationship between the macromechanical behaviour and the microstructural parameters by using micromechanics.The experimental technic of micromechanics and its basic theory were introduced.The developments of the micromechanical models were presented.Then the developments of the numerical simulations,based on finite element method,of the mechanical behaviour were reviewed.Finally,the developing trends of this subject were discussed.更多还原
