| Abstract Scope |
Many natural and biological materials have underlying disordered structures that play a central role in determining their properties. This is in contrast with most engineered architected materials, which are comprised of repeating unit cells. While periodic structures allow materials with exceptional elastic/dynamic properties to be realized, disordered architectures offer opportunities to enhance failure behavior. Through a combination of finite element modeling and experiments on model systems (architected polymer materials), we have investigated how the failure properties of network materials can be tailored through the introduction of disorder. Disorder can be exploited to increase toughness and damage tolerance, but if introduced in an uncontrolled manner can reduce strength. Our results, however, also show that controlled disorder, determined via a combination of modeling and optimization approaches, can lead to increases in toughness with minimal or no loss in strength. The results are compared to examples found in nature. |
