Carlos Dávila

Carlos G. Dávila, PhD

Senior Aerospace Researcher
NASA Langley Research Center, Hampton (Virginia)

Carlos Dávila is a Senior Aerospace Research Engineer at the Structural Mechanics and Concepts Branch at the NASA Langley Research Center in Hampton, Virginia. He obtained his Ph.D. degree in Aerospace Engineering in 1991 from the Virginia Polytechnic Institute. Upon graduation, he went to work at the NASA Langley, first as a National Research Council Associate, then as an employee of the Vehicle Technology Directorate of Army Research Laboratory, and finally as a NASA Civil Servant.

He has served as a structural analyst in several accident investigations, including a fatal fracture in a US Army helicopter and the fracture of the fin lugs in the American Airlines Airbus A300 2001 accident investigation. His research interests include the development of finite element methods for the prediction of damage propagation and residual strength of metallic and composite structures. He is the recipient of the NASA Exceptional Technical Achievement Medal for his work on damage models for composite materials.

His keynote is entitled "Advances and New Applications for Softening Laws".

Advances and New Applications for Softening Laws

The goal of predicting the strength and damage tolerance of composite structures with robust and reliable computational models appears to be reachable. Recent advances in the understanding of cohesive methods, combined with their availability in most commercial finite element software has resulted in a widespread interest in the application of progressive damage analysis methods in detail design.

In this presentation, we examine the conditions under which cohesive and softening laws can be applied to progressive damage analysis and be expected to work as intended. The issues of size effects and the ability of cohesive laws to represent correct load path redistributions are discussed. In particular, recent work on scale effects has shown that the shape of the cohesive laws can be determined from the R-curve toughening response of the material or by performing J-integral contour calculations using digital image correlation. Results will be shown for cohesive laws developed for the mixed-mode fracture of adhesive joints, as well as laws that account for the blunting effects of fiber bridging and splitting cracks. Finally, new applications of cohesive laws to continuum damage models based on the rotating crack concept as well as the extended finite element method (X-FEM) will be discussed.

In spite of great progress over the past 10 years, mixed-mode fracture remains one of the great challenges for cohesive laws. Newly uncovered complexities associated with load path histories will be presented. Experiments and analyses show that most mixed-mode fractures initiate in mode II and end in mode I. Predicting mixed-mode fracture can expose large differences among different formulations and some of the conditions necessary to obtain good predictions will be presented.

He is currently finalizing the 2nd edition of his undergraduate textbook and working on a book chapter about physical aging of polymer composites, as well as being engaged in several research projects in materials science.

His keynote is entitled "Modeling and Experimental Strategies for Predicting Intralaminar Damage in Laminated Composites".

Modeling and Experimental Strategies for Predicting Intralaminar Damage in Laminated Composites

Intralaminar damage in laminated composites is not only the first mode of damage encountered in most applications but also it precipitates other catastrophic modes of failure, such as delaminations and fiber fracture. Also, intralaminar cracks are responsible for drastic increases of permeability, which exposes the fibers and the interlaminar interfaces to environmental attack, such as moisture, and thermomechanical loading by cryouids, as well as compromising the imperviousness of the structure.

Therefore, accurate prediction of initiation and evolution of intralaminar matrix cracks is fundamental for the prediction of ultimate material and structural strength, fatigue life, and so on. Along these lines, an overview of the available modeling strategies will be presented, with a discussion of limitations, advantages, and disadvantages of each methodology. Further details will be discussed about the most salient techniques in an effort to elucidate the role of each of them. In addition, a novel application of the acoustic emission technique, correlated against X-ray images, will be summarized. The experimental results will then be used to propose a methodology for experimental determination of the invariant material parameters, i.e. fracture toughness, needed for modeling.

Desarrollos de Estructuras Aeronáuticas en Materiales Compuestos

Las aeroestructuras han incorporado progresivamente componentes de mayor tamaño e integración empleando materiales compuestos. Esta evolución se ha basado en una sostenida mejora de prestaciones de materia prima, un mejor conocimiento de su potencial y del desarrollo de medios industriales capaces de dar respuesta a los requerimientos aeronáuticos.

Los aviones de transporte siguen demandando soluciones que sean a la vez imaginativas, fiables e industriales. En la actualidad, los principales retos relativos a conjuntos estructurales se pueden ilustrar por medio de desarrollos en secciones de fuselaje y superficies sustentadoras. Se describen varios ejemplos en los que se recorre el camino desde el Diseño a la Producción, empleando metodologías de Ingeniería Colaborativa. Se exponen algunas de las claves para conseguir que los saltos tecnológicos puedan afrontarse con la puntualidad que el mercado exige.

Carlo Paulotto

Dr. Carlo Paulotto

Head of the Design Group at the Infrastructures Department
Centre for Technological Innovation, Acciona Infraestructuras

Carlo Paulotto, member of ACI and IIFC, is head of the desgin group at the Infrastructures Department of the Acciona Infraestructuras Centre for Technological Innovation, Madrid. He received his Ph.D. in Structural Engineering from the University of Rome “La Sapienza“ in 2004. In the 2005-2007 biennium he did a fellowship at the European Laboratory for Structural Asessment of the European Commission at Ispra (Italia).

In 2007, he joined Acciona Infraestructuras as a research engineer in the field of composites application in infrastructures. He has been involved in the design and mechanical tests of composite bridges and pedestrian bridges built and installed by Acciona Infraestructuras.

His keynote is entitled "Mechanical tests on the CFRP cables of a stress - ribbon pedestrian bridge".

Mechanical tests on the CFRP cables of a stress - ribbon pedestrian bridge

In 2011, in the Spanish city of Cuenca, Acciona Infraestructuras built a pedestrian bridge that belongs to that class of structures named stress-ribbon bridges. In this type of bridges, the main load bearing system is formed by are a series of tensioned cables that directly support the reinforced concrete deck. In the case of the pedestrian bridge erected in Cuenca, these cables, which are normally made by steel, were manufactured using a composite material compounded by carbon fiber tows and epoxy resin.

This type of composite material cables is nowadays popular in sailboats rigging cordage. The cables used in the construction of the pedestrian bridge have a diameter much greater than those of the cables currently employed in sailboats, since the magnitude of the loads the cables need to resist is very different for these two applications. Due to the novelty of the use of this type of cables in bridge construction and the considerable difference existing between their diameter and those of the cables normally produced for the naval industry, it was decided to carry out a series of tests to assess their mechanical behavior. The results of these tests (direct tension tests and deviated tension tests) are presented.
