Structural analysis procedures and predictions of the physical behavior of complex structures with heterogeneous materials are usually based on the well‐known and established numerical homogenisation techniques with effective stress and material parameters, i.e. FE2methods with effective and . The general goal is to enhance these methods with elements from variational sensitivity analysis and to formulate optimisation problems with objective functions, constraints and design parameters on multiple scales. The focus of this contribution is the sensitivity analysis of effective stresses or the corresponding Langrange multiplier 𝛌 respectively, which is incorporated in solution strategies based on the Lagrange formalism, as presented in [3] or [4]. The obtained sensitivity information can be used to setup optimisation problems for individual microscale representations and to control effective parameters within the overall optimisation procedure on single scales.
