By means of molecular dynamics simulations, we study the behaviour of lamellae forming diblock copolymer and nanoparticle mixtures in thin‐film geometry under stationary shear. In particular, we investigate the system under transverse mode of shear considering both nonselective and selective types of nanoparticles. We find that the presence of nanoparticles affects the critical shear rate at which the lamellar morphology is not stable during transverse shear and orientation transition sets in. We also study the spatial distribution of nanoparticles in the presence of flow field and its effect on the macroscopic response of the system.
