A Novel Multiscale Design of Interfaces for Polymeric Composites and Bonded Joints using Additive Manufacturing
Abstract
Develop computational framework for designing optimum interfaces for layered composites to minimize damage and failure when subjected to static and dynamic mechanical loads as well as extreme thermal loads. Develop a novel upscaling methodology to account for the influence of interface stiffeners on the macroscale failure behavior of the composite. Investigate the feasibility of using additive manufacturing for constructing micro scale interfaces on composite prepregs. This will include the construction of interfaces with spatial variation to reduce effects like, edge effects on the interface delamination mechanism and damage due to high intensity impact. Develop smart designs for bonded joints in aircrafts using the above developed computational design methodologies.
