    A numerical study of progressive damage in unidirectional composite materials using a 2D lattice model
    (Elsevier, 2021-05-15) Braun, Matías Nicolás; Iváñez del Pozo, Inés; Ariza, M.P.
    In this study, we explored the effects of different softening laws on the modelling of progressive damage in unidirectional composites materials using a 2D lattice model. The lattice model was based on axial springs that accounted for nearest-neighbour interactions. We considered linear and exponential softening laws and assessed their influence on the dynamic fracture response of unidirectional composite materials using two numerical examples. In order to overcome one of the drawbacks inherent to lattice models, i.e., the dependence on lattice cell size, we modified the material constitutive law by introducing a characteristic length parameter. The results obtained are also compared with experimental data reported by other researchers.

    Towards a Life Cycle Sustainability Assessment method for the quantification and reduction of impacts of buildings life cycle
    (Iop Publishing Ltd, 2019-08-01) Llatas, C; Angulo Fornos, R.; Bizcocho Tocón, Nuria; Cortés Albalá, I; Falcón Ganfornina, R.; Galeana, I; García-Martínez, Alberto; Gómez de Cózar, J.C.; López Alonso, S.; Meda, P.; Ministerio de Economía y Competitividad (España)
    The construction and building sectors are one of the highest consumers of resources and energy. Literature evidences the potentialities of the design phase towards the improvement of environmental, economic and social performance of buildings. Thus, the Life Cycle Sustainability Assessment (LCSA). approach is recognized as suitable method. It is based on the 'triple bottom line' principle, to calculate environmental, economic, social impacts produced by buildings during its life cycle. The present paper aims to present a methodological framework based on an LCSA, used during design stages of buildings and integrated into a building's design technology such as Building Information Modeling (BIM). A conceptual approach to conduct the data integration and a possible workflow to integrate the LCSA into BIM is proposed. The value of the present approach is the possibility to conduct quantitative environmental, economic and social assessment of buildings to guide designers to measure and predict the building's performance.
