Title: An Integrated Computational & Experimental Material Design Framework: Elucidating the Competing Failure and Deformation Mechanisms Abstract: Attainment of both high strength and high toughness in structure materials is a fundamental challenge in material science since these 2 properties tend to be mutually exclusive. A material design space which allows microstructure-property predictions through energy pathway control holds 1 of the keys for the next-generation material design. This approach provides an innovative way in understanding the energy dissipation mechanisms and their intricate coupling with material deformation and fracture through multiscale simulations and in-situ Digital Image Correlation (DIC) analysis. Conclusions from this study can provide physical insight and a general guideline of effectively tailoring the microstructures to achieve desirable material properties by redistributing energy dissipations in controllable paths.
