Damage assessment for 2D multicracked materials/structures by using mc-integral / Chang, Jui-Hung in Journal of engineering mechanics, Vol. 135 N° 10 (Octobre 2009) 

Public ISBD [article]  in Journal of engineering mechanics > Vol. 135 N° 10 (Octobre 2009) . - pp. 1100-1107 Titre : Damage assessment for 2D multicracked materials/structures by using mc-integral Type de document : texte imprimé Auteurs : Chang, Jui-Hung, Auteur ; Liu, Dau-Ying, Auteur Article en page(s) : pp. 1100-1107 Note générale : Mécanique appliquée Langues : Anglais (eng) Mots-clés : Cracking  Strain  energy  Damage  Assessment  Stiffness  Elasticity. Résumé : An efficient method is presented to characterize the damage state for two-dimensional multicracked elastic solids. This method is based on the concept of a path-independent Mc-integral, through which the surface energy associated with creation of all the cracks is evaluated. On one hand, when the cracked media are homogeneously stressed, the correspondence relation between the effective material moduli and Mc is established. On the other hand, when the cracked solids are nonhomogeneously stressed, the effective structural stiffness is determined by using the result of Mc. Through proper use of Mc, the damage state of the cracked structure can be assessed both qualitatively and quantitatively.
