A Novel Method to Estimate the Damage Severity Using Spatial Wavelets and Local Regularity Algorithm

Mallikarjuna Reddy, Arun Kumar K

In the process of structural damage detection using continuous wavelet transform (CWT), the perturbation or damage is located by identifying the defects locally in the input signal data. In this work the damage identification procedure…

The effect of creep damage model formulation on crack path prediction

Valery Shlyannikov, Andrey Tumanov

The stress, strain rate and process zone with respect to the creep-crack growth are analyzed by employing damage-evolution equations. The damage models for the fracture of the process zone are represented using a stress and ductility based…

Damage evaluation under complex fatigue loading conditions

Luis Reis, Joao Caxias, Henrique Soares, Pedro R. Costa, Vitor Anes, Manuel Freitas

Fatigue damage and life assessment of multiaxial loadings is still an issue yet to resolve. Many methods have been proposed with promising agreements with the experimental results. However, the performance of such methods is, more than…

Shear behaviour of reinforced concrete beams under impact loads by the lumped damage framework

Mateus Oliveira, Daniel Teles, David Amorim

Impact loadings such as vehicle collisions or falling rocks on a structure could lead it to collapse and, eventually, to fatal victims. Among possible alternatives to analyse this issue, Lumped Damage Mechanics is an interesting option due…
