Using a one-dimensional model that takes into account ideal plasticity of the surface layer, we investigate the fragmentation of thin coatings under uniaxial tension. The coating is modeled as a chain of plastically deforming elements that are connected via leaf springs to a uniformly stretched substrate. Each coating element can only withstand a maximum(More)
Nanoparticles are essential building blocks for nanotechnology. In this paper we demonstrate a novel method to create nanoplatelets by thin film cracking. The thickness of the resulting platelets is determined by the film thickness, and their aspect ratio is controlled by the total strain and the elastic mismatch between substrate and thin film. Platelets(More)

We experimentally investigate the breakup of an equibiaxially elongated polystyrene (PS) drop in a poly(methyl methacrylate) (PMMA) matrix during relaxation after melt elongation. In equibiaxial elongation, the initially spherical PS drop is deformed into an ellipsoidal disclike shape for our test parameters. Using a hotstage in combination with a light(More)
