The results indicate that the deformation characteristics before the peak load in Brazilian split tests are similar to those of uniaxial compression test which could be divided into four stages, namely compression, elasticity, yielding and failure stage. AE events in compression and elasticity stage are totally low in energy and accumulation number. Starting from the yield stage, AE events increase rapidly, and energy and accumulation number grow quickly. The specimens suddenly fracture when the load exceeds capacity, and the residual stress rapidly disappears. In this test, the sign for specimen failure could be judged through observing ringing counting, accumulation number and energy, so as to provide reference for engineering practice., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null, articleAbsUrl=null, sourceXml=null, magXml=null, pdfUrl=null, pdf=W+JinW9TGL04xvV9vydAYQ==, pdfFileSize=1715722, pdfExtLink=null, richHtmlUrl=null, mobilePdfUrl=null, reviewReport=null, pdfFirstPage=null, abstractGraph=null, abstractGraphContent=null, abstractVideo=null, citation=null, cebUrl=null, magXmlContent=null, mapNumber=null, authorCompany=1.
