FRACTURE MECHANICS APPROACH TO MIXED-MODE FRACTURE OF CONCRETE : Basic examination on the crack propagation of notched concrete beams under mixed-mode loading conditions

Abstract

The objeCtive of this paper was te darify the ilfiuence of mixed − mod じ load 血 g collditions on the load − dofomation relationships and the craok propagation of netced ooncrete bea皿 specinen ． Mixed − mode ioadillg co 皿ditions were made by changing thc distan ffom 血 e load 血 g linc to the notch line of the specimen ． Crack propagation of the s ρ edmen was observed and i［ was compared w 壷 〔 h the resUlt of analysis which was based on the linear elastic fraCture mecha 血cs (
