This paper deals with the second-order computational homogenisation of a heterogeneous materiał under-going smali displacements. Typically, in this approach a representative volume element (RVE) of nonlinear heterogeneous materiał is defined. An a priori given discretised microstructure is considered, without fo-cusing on detailed specific discretisation techniąues. The key contribution of this paper is the formulation of eąuations coupling micro- and macro-variables and the definition of generalized boundary conditions for the microstructure. The coupling between macroscopic and microscopic levels is based on Hill's aver-aging theorem. We focus on deformation-driven microstructures where overall macroscopic deformation is controlled. In the end a numerical example of a thin layer shear is presented.
