By using the experimental system and the UV flatbed printing technology, a blasting model experiment on polycarbonate (PC) plate is conducted, the evolution of blasting strain field and the attenuation law are analysed. The results show that the compressive wave is the main form of blasting stress wave and the shear wave is the minor form. With the propagation of stress wave in the specimen plane, the stress wave decays from high frequency to low frequency, and the energy of stress wave dissipates gradually. In addition, the ABAQUS finite element analysis code is used to simulate the dynamic process of blasting. The deformation evolution of numerical simulation is in good agreement with the experimental results, it is verified that the experimental system has good applicability to blasting research., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null, articleAbsUrl=null, sourceXml=null, magXml=null, pdfUrl=null, pdf=GHgYLVq/nwQJuVf/Me/WTg==, pdfFileSize=3909251, 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.
