<b>An Integrated Physics-Based Multiscale Modeling Framework for Advancing Thermoset Composites Manufacturing Processes</b>Ryan Scott Enos (20449379) 19 December 2024 (has links)
<p dir="ltr">The manufacturing of composite materials presents numerous opportunities due to their superior properties, including high strength-to-weight ratios and excellent fatigue resistance, which make them ideal for advanced engineering applications. However, realizing these advantages is challenging due to complexities in manufacturing processes, which can introduce defects, residual stress, and variability. This study aims to address these challenges through the development of integrated, physics-based processing models that are capable of predicting and mitigating manufacturing defects in advanced composites. The research focuses on the integration of these physics-based models with data-driven methods such as statistical analysis, uncertainty quantification, and optimization. A significant emphasis is placed on modeling the thermo-viscoelastic (TVE) behavior of curing composites, which is often simplified in processing simulations due to computational costs, by approximating to elastic responses according to the Cure Hardening Instantaneously Linear Elastic (CHILE) model. Results show that cure-dependent TVE process simulations implemented through Finite Element Analysis (FEA) can be efficiently integrated with optimization algorithms. 570 simulations completed in 109 min on a local desktop computer. Building on these advancements, this work further investigates Automated Fiber Placement (AFP) under the context of Integrated Computational Materials Engineering (ICME), and establishes the groundwork and serves as roadmap for AFP research at Purdue University with a focus on process modeling and integration.</p>

Confusio hos AugustinusBårman, Erik January 2024 (has links)
Denna uppsats börjar i tänkandet hos Augustinus, som förutom med hans egen definition av tänkandet som ett samlande också ser tänkandet som ett välvande [volvere] och ett fusionerande [fusio]. Tänkandet som ett välvande sker genom att ord revolverar [revolvere]. Detta leder till upptäckten av att vara involverad [involvere] i världen. Eftersom man är involverad vill man försöka evolvera [evolvere] det i vilket man är involverad: strukturen är volvere–revolvere–involvere–evolvere. Detta hänger samman med varats utgjutning [diffusio] som ingjuts [infusio] i människorna, varför människan ur förskingring vill fusionera [fusio] sin verklighet. Ur detta uppstår confusio. Hos Augustinus bestäms människan av ett tredelat confusio: kosmologiskt som upphov, biologiskt som skam och kognitivt som förvirring. / The following thesis takes as its point of departure the implicit Augustinian view of thinking. Besides his own definition of thinking as a ”collecting” in the Confessions (and his view of thinking in On the Trinity), Augustine also suggests thinking as volving [volvere]. This kind of thinking is structured by words revolving [revolvere] in the mind. This, is suggested, by necessity leads to an involvement [involvere] in the world. The fact of being involved in the world also means striving to evolve [evolvere] that in which you are involved: the structure is volvere–revolvere–involvere–evolvere. This, in turn, is due to ”being” being diffused [diffusio], which then is infused [infusio] into human beings. As a result, the human being tries by thinking to fuse [fusio] reality from dispersion into unity. From this, confusion [confusio] emerges. Here, the structure is diffusio–infusio–fusio–confusio. The aim of this thesis is to envelope and place what for Augustine is predominantly a negative notion of confusio in the right manner as a generative and dynamic notion, structured in a threefold manner: cosmologically as origin, biologically as shame, cognitively as confusion. These being three aspects defining the ego.
