Experimental-Numerical Hybrid Reinforcement Characterization Framework,logy is described in detail in the following sections.?Specific details about the hardware accessories and software packages used in the virtual permeability predictions are presented. All the three modeling approaches i.e. realistic, stochastic and ideal, are used in different applications.

Experimental-Empirical Hybrid Approach, Any complex structure is broken-down into simple regions and usb-regions with a “divide and conquer” strategy. The overall?equivalent permeability is then estimated?by summing up the permeability of?the individual regions in a bottom-up sequence.?

Generation of Material Twin Using Micro CT Scanning,ection, the numerical simulation technique for virtual permeability computation is discussed which includes, establishing governing equations and boundary conditions, followed by identifying a suitable algorithm to solve governing equations on the discretized geometry, and obtaining reinforcement permeability through Darcy’s Law.
