| Abstract Scope |
Micron scale structures or microstructures have become strongly coupled with their macroscopic counterparts in determining the bottom-up and top-down multiscale structural behavior with the advent of advanced manufacturing technologies such as additive manufacturing and castforging due to the spatiotemporal scales at which their fabrication driving forces operate. This coupling necessitates solving the single grain length scale problem with aspects of slip and twin systems appropriately captured to effectively simulate the steady state and transient behavior respectively. Although due to the spatiotemporal discretization, it is impossible to simulate large polycrystalline or subsequently the part scale structural behavior, thereby establishing the requirement for an Integrated Computational Homogenized Multiscale Structural approach. In response to this requirement, a generalized formulation with scale coupling coefficients effectively capturing the spatiotemporal characteristic dimension along with the distribution of physical and numerically computed mechanical properties such as the elastic and tangent moduli will be discussed during this talk. |
