Measurement of continuous damage parameter

Engineering Fracture Mechanics, 1988
Abstract The present paper introduces several measuring methods of continuous damage parameter derived by the classical definition D = 1 − (A e /A a ) : (1) The measuring method on the basis of D = 1 − (E'/ E) ; (2) The measuring method on the basis of D = 1 − (ϵ 1 /ϵ 2 ) ; (3) The measuring method on the basis ...

Evaluation of a seismic damage parameter

Earthquake Engineering & Structural Dynamics, 1999
Several parameters have been proposed in the literature for the evaluation of seismic damage. However, in most cases the correlation between results obtained using these parameters and observed damage in structures has not been satisfactory. A parameter for measuring seismic damage previously proposed by the first author is used in this study to ...

Critical parameters for fatigue damage

International Journal of Fatigue, 2001
Abstract The fatigue damage analysis is examined from a historical perspective. The analysis indicates that some of the issues concerning the basic disparities between the experiment and model/interpretations. To help understand these issues, we have developed an approach with two driving force parameters to analyze the fatigue behavior.

MICROCRACK PROPAGATION AND MICROSTRUCTURAL PARAMETERS OF FATIGUE DAMAGE

Fatigue & Fracture of Engineering Materials & Structures, 1996
Abstract— Modern approaches to microstructural analysis of fatigue in metallic materials consider the density and the total length per unit area of propagating surface microcracks as useful indicators of fatigue damage. Such parameters, when observed on a carbon steel studied in a previous paper, have a dispersion similar to that of fatigue life and ...

Damage parameter identification by a periodic homogenization approach

Computational Materials Science, 2002
Abstract The determination of model parameters describing damage evolution within the continuum damage approaches by Tvergaard–Needleman and Rousselier is investigated. For this, adressing materials with small initial damage, finite element simulations were carried out on the mesoscale for single voided periodic unit cells.

Vibrodiagnostic parameters of fatigue damage in rectangular plates. Part 1. A procedure of determination of damage parameters

Strength of Materials, 2004
We describe a procedure of approximate analytical determination of fatigue damage parameters of rectangular plates. As an initial damage characteristic we apply the relative value of the plate potential-strain-energy variation due to availability of a Mode I crack, and, based on this value, we find relations for determination of the plate natural ...
