Extrapolation of AR models using cubic splines for damage progression evaluation in composite structures
(2021-02-01)
This paper presents the potentiality of the use of extrapolation of a set of Auto-Regressive (AR) models to inspect a future damage sensitive indices based on changes in one-step-ahead prediction errors. The key idea is ...
Autoregressive model extrapolation using cubic splines for damage progression analysis
(2021-01-01)
The application of Structural Health Monitoring (SHM) methods focuses mainly on its initial levels of the hierarchy of damage identification. The contribution of this paper is to propose a new strategy that allows going ...
Progression of articular and extraarticular damage in oligoarticular juvenile idiopathic arthritis
(Clinical & Exper Rheumatology, 2011-09-01)
Objective Evaluate damage in oligoarticular JIA, estimating its frequency, risks and probability over time.Methods A cross-sectional and retrospective analysis of Juvenile Arthritis Damage Index (JADI) scoring, with both ...
A numerical study of progressive damage in unidirectional composite materials using a 2D lattice model
(Pergamon-Elsevier Science Ltd, 2021-05)
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 ...
A progressive damage based lattice model for dynamic fracture of composite materials
(Elsevier, 2020-11)
In this paper we present an extension of the linear elastic lattice model for anisotropic materials previously developed by the authors. This approach takes into consideration damage evolution in composite materials by ...
A new damage model for composite laminates
(ELSEVIER SCI LTDOXFORD, 2013-08-02)
Aircraft composite structures must have high stiffness and strength with low weight, which can guarantee the increase of the pay-load for airplanes without losing airworthiness. However, the mechanical behavior of composite ...
