Abstract: Multiscale materials modeling promises to yield ever greater accuracy to methods to assess the service performance of material solutions. In addition, Integrated Computational Materials Engineering (ICME) workflows and data-driven methods are foreseen to enable the performance driven design of novel materials for demanding environments and applications. In current work ICME concepts and several use cases are presented targeting improved service performance assessment and the development of methodologies to systematically design and ultimately optimize targeted material solutions to specific applications, components and products. To that effect, use cases are presented ranging from mechanical material performances (such as fatigue and fracture) to complex loading conditions (tribological contacts, erosion-corrosion and corrosive environments). Also, performance design aspects are addressed by introducing data-driven and hybrid modeling concepts (see Figure below) driven by virtual performance testing methodologies especially at the microstructural scale employing micromechanical modeling. The results demonstrate how multiscale materials modeling can be exploited in better understanding of material performances as well as address material design by hybrid modeling enriching the capabilities of physics-based modeling, as an outcome targeting novel and improved material solutions.
