Abstract: With the increasing development in computing power have come the introduction of sophisticated tools for the analysis of composite structures. Integrated Computational Materials Engineering (ICME) is a new branch of mechanics intended to transform the design and manufacturing of future advanced composites and drastically reduce time and cost of engineering programs. Within ICME, it is increasingly recognized that the manufacturing process influences the microstructure of a material which in turn dictates performance. This talk will focus on the description of modeling tools for the analysis of virtually cured fiber‐reinforced thermoset structures capable of predicting the variations which occur during manufacturing. Different modeling techniques are used respectively at the nano‐, micro‐ and macro‐scale including Molecular Dynamics, traditional and Higher‐Order Finite Elements (FE). Continuum damage models are used to perform progressive and macro‐scales and virtually characterize the mechanical properties of thermoset composites.

Bio: Marianna Maiaru (Assistant Professor in Mechanical Engineering, UMass Lowell) is an expert in development of computationally light multi‐scale approaches for the progressive failure analysis of fiber‐ reinforced composite structures using higher‐order FEM. Her research interests include composite structures, computational mechanics, Integrated Computational Materials Engineering (ICME), multi‐scale analysis, composite manufacturing, molecular‐dynamics, Finite Element Analysis (FEA), Higher‐order FEA and Additive Manufacturing. Before joining the faculty at UMass Lowell, Maiaru was a Research Associate in the William E. Boeing Department of Aeronautics & Astronautics at the University of Washington and, before that, a Research Associate in the Department of Aerospace Engineering at the University of Michigan. Her post‐doctoral research, sponsored by AFRL, has been conducted in collaboration with many aerospace industries and focused on the development of physics‐ based models of the manufacturing induced effect on polymer matrix composites (PMCs).
