Abstract
The development of models for a priori assessment of the reliability of micro electromechanical systems(MEMS) is of crucial importance for the further development of such devices. In this contribution apartition of unity-based cohesive zone finite element model is employed to mimic crack nucleationand propagation in a piezoelectric continuum. A multiscale framework to appropriately representthe influence of the microstructure on the response of a miniaturised component is proposed. Itis illustrated that using the proposed multiscale method a representative volume element exists.Numerical simulations are performed to demonstrate the constitutive homogenisation framework
