This presentation will showcase experimental and theoretical approaches being developed at the University of Texas Arlington Advanced Materials and Structures Lab (AMSL) for microstructural characterization needed for design, qualification, production, and sustainment of advanced composite materials and structures. These innovations are based on the development, and most importantly effective integration, of the following elements. First, high-resolution nondestructive inspection and structural diagnostics are enabling objective 3D measurement of material structure including location and size of manufacturing irregularities. with automated transition to structural and microstructural models. Second, effective methods are capturing essential in-situ material constitutive properties to complete the input data requirements for comprehensive strength/fatigue models. These methods capture physics of the investigated phenomena including stress-strain response, strength/fatigue and toughness material characteristics. Third, the physical observations and material properties are combined in a computational analysis to capture multiple damage modes and their interaction and predict material performance and structural integrity.
