Deformation and Mechanical Behavior of Transparent Nanoscale Multilayers
Abstract
Deformation and Mechanical Behavior of Transparent Nanoscale MultilayersThe overarching research objective is to characterize the deformation and mechanical properties of transparent nanoscale multilayers (NMs) in order to correlate the bilayer thickness and interface type to the mechanical performance. This research project will provide the fundamental science for understanding the relationship between deformation mechanisms, length-scale effects, interface effects and transparency in ceramic/ceramic and ceramic/metal multilayers. Specifically, the scientific objectives will be pursued by employing novel synthesis techniques for NM deposition, which allow flexible shape designs for mechanical testing, under a wide range of deformation modes which will be used to develop a comprehensive guide for the mechanical behavior of transparent optical multilayers. These studied combinations will serve as the baseline for future design of non-metallic multilayers with the ultimate goal of designing and synthesizing new high-performance, long-lasting optical engineering materials that will reduce the cost of ownership of essential equipment needed for DoN missions. More specifically, this project aims to bridge a current significant knowledge gap regarding the deformation of non-metallic multilayers by focusing on a subset of important optical NM materials. Directing the research towards transparent optical multilayers provides a finite selection of materials with a large window of transmission from UV to mid-IR wavelengths and beyond. These materials have broad Naval applications such as transparent load-bearing armor, high durability windows and face shields, sensor windows, transparent windows that are scratch resistant and self-cleaning, as well as windows with spectral selectivity.
