They give a new insight into the fracture process zone, leading one to presume that during the crack propagation the crack opening is restrained. So, the crack opening cannot increase without an energy dissipation that has to be added to the one from the crack propagation. Generally, measurements of fracture energy per unit of crack surface give rise to size dependent values for mortar and concrete. We propose a simple model that takes into account the energy dissipated by restrained crack widening (RCW), with the aim to verify if it can explain the size dependence on the energy dissipated per unit of crack surface. The theoretical predictions from the proposed model and the experimental dissipated energy per unit of crack surface obtained by means of RILEM TC-50 procedure are in good agreement. So, size dependence could be mainly explained through the concept of RCW.</p></div>","PeriodicalId":100028,"journal":{"name":"Advanced Cement Based Materials","volume":"4 3","pages":"Pages 77-92"},"PeriodicalIF":0.0,"publicationDate":"1996-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S1065-7355(96)90077-2","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72242719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three methods of fracture testing are examined in the perspective of the size effect, and the merits and weaknesses of various methods in regard to the size effect are pointed out.

The paper contains a description of an experimental setup that allows measurement of the clamping pressure, which develops on an elastic inhomogeneity embedded in a matrix consisting of a cementitious material undergoing shrinkage during hydration (autogenous shrinkage). Furthermore, the paper presents the analysis necessary to perform an interpretation of the experimental results and to determine the clamping pressure acting on any elastic inhomogeneity embedded in the same cementitious matrix material. Fiber-shaped inhomogeneities are of special interest in cementitious composite material systems, and results are presented for the development of clamping pressure on three typical fiber types in two typical cement pastes used in high performance cementitious composite materials. Assuming a Coulomb type of friction on the fiber-matrix interface and using typical values for the frictional coefficient, it is shown that the shrinkage-induced clamping pressure could be one of the most important factors determining the frictional stresses observed on debonded fiber-matrix interfaces during pullout.</p></div>","PeriodicalId":100028,"journal":{"name":"Advanced Cement Based Materials","volume":"4 3","pages":"Pages 106-115"},"PeriodicalIF":0.0,"publicationDate":"1996-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S1065-7355(96)90079-6","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72242718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
