A multigrid method for the solution of composite mesh problems
(Planta Piloto de Ingeniería Química, 2015-01)
The Composite Finite Element Mesh method is useful for the estimation of the discretization error and, in addition, for the nodal solution improvement with a small increase in the computational cost. The technique uses two ...
Free vibration of single and sandwich laminated composite plates by using a simplified FSDT
(Elsevier, 2015-11)
This paper presents a simplified first order shear deformation theory (FSDT) for laminated composite and sandwich plates. Unlike the existing FSDT, the present one has a novel displacement field which include undetermined ...
Effect of staining agents on color change of composites
(2012)
Composite resins are materials that can present color changing when exposed to pigments. Objective: The aim of this study was to evaluate, in vitro, the color changing of composites after immersion in different substances ...
Corrosion and tribocorrosion behaviour of Al-Si-Cu-Mg alloy and its composites reinforced with B4C particles in 0.05M NaCl solution
(2013-08-30)
The corrosion behaviour of metal matrix composites (MMCs) is strictly linked with the presence of heterogeneities such as reinforcement phase, microcrevices, porosity, secondary phase precipitates, and interaction products. ...

Roughness and morphology of composites: influence of type of material, fluoride solution, and time
(2014)
This study evaluated the effect of fluoride solutions on surface roughness and morphology of composites in the short and long term. Specimens were randomly assigned to experimental groups (n=5) according to type of composite ...
Carbon nanotubes/polyamide 6.6 nanostructured composites crystallization kinetic study
(2013-08-01)
Compared with the traditional composites, the incorporation of carbon nanotubes into polymeric matrices can generate materials with superior properties, especially thermal, electrical and tribological properties. The aim ...

Evaluation of marginal microleakage in Class II cavities: Effect of microhylolrid, flowable, and compactable resins
(Quintessence Publ Co IncCarol StreamEUA, 2003)
Composite mesh concept based FEM error estimation and solution improvement
(Elsevier Science Sa, 2000-03)
The use of composite finite element models where meshes with different granularities are allowed to share the same problem domain, is introduced. The idea of this method was taken from the mixture theory of multiphase ...
