Effect of bituminous impregnation on nonwoven geotextiles tensile and permeability properties
(ELSEVIER SCI LTD, 2011)
Geosynthetics interlayer systems are effective techniques to control reflective cracking in damaged pavements. It comprises the inclusion of nonwoven geotextiles between the damaged layer and the new overlay of the pavement ...
Aplicação da metodologia numérica “fast bounds crack” para uma estimativa eficiente da evolução do tamanho de trinca
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Mecânica e de MateriaisUTFPR, 2015-11-03)
A significant part of the life of a mechanical component occurs, the crack propagation stage in fatigue. Currently, it is had several mathematical models to describe the crack growth behavior. These models are classified ...
Estabelecimento de cotas para os momentos estatísticos do tamanho de trinca, para o modelo de Collipriest via método Fast Crack Bounds
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Mecânica e de MateriaisUTFPR, 2017-09-18)
In a realistic approach of structures and mechanical components, cracks are admitted. Their presence is usually associated with the fatigue phenomenon. There are several mathematical models that describe the propagation ...
A boundary element method formulation to capture strong discontinuities in solids
(2005-12-01)
A Boundary Element Method (BEM) formulation to predict the behavior of solids exhibiting displacement (strong) discontinuity is presented. In this formulation, the effects of the displacement jump of a discontinuity interface ...
Mechanical strength and subcritical crack growth under wet cyclic loading of glass-infiltrated dental ceramics
(Elsevier B.V., 2010-05-01)
Objectives. Evaluate the flexural strength (sigma) and subcritical crack growth (SCG) under cyclic loading of glass-infiltrated alumina-based (IA, In-Ceram Alumina) and zirconia-reinforced (IZ, In-Ceram Zirconia) ceramics, ...
